I have a new install of Excel 2016, that hates CSV files. It opens them with everything in one column flagpole style, down column A, with commas and speech marks visible.
Salient points:
I have two machines, desktop and laptop, both running same version of Excel. Desktop works fine, opens the same problem files formatted correctly.
I can create CSV files on laptop, save those, open them again on laptop, and it's fine.
Even opening it in Notepad++, saving in the hope of some sort of file format normalisation, and still no good.
I have compared regional settings and almost all settings in Excel.
I tried renaming the file to TXT, it brought up the text file conversion dialogue, I chose comma delimited. First time it ignored that, still got everything in column A, second attempt, that actually worked, however, that is a pants solution, I want to be able to just natively open CSV files without saving as TXT, I use many different ones every day.
Anyone got any ideas?
Thanks in advance.
CSV files are character separated value files, not necessarily comma separated. For more than half the world the separator character is a semicolon (;), not a comma (,)
Excel 2016 properly respects your Windows regional settings, and uses the specified List Separator character
One solution is to change your regional settings for the List Separator attribute to the character you want Excel to default to using, e.g. a comma (,)
This can be changed in the operating system Control Panel, under Region settings, Additional Settings, List separator
For various reasons some people seem to have the incorrect regional settings for the culture they most commonly work in, and therefore have semicolon as the default separator
If you prefer not to change your operating system regional setting to what you think is normal for CSV files, you can change the default behavior in Excel with the Use system separators checkbox under the File/Options/Advanced menu
If you want custom options each time you open a CSV file, use the Data/From Text menu, but this becomes slow and awkward for lots of files

I've found a way of saving messy CSV files into a nice table format but I'm not sure if it will work for your case.
Data -> New Query -> From File -> From CSV
By opening the CSV file this way, a pop-up 'Query Editor' window will appear with a nicely organised table format where you can edit, save and load into your excel sheet.
I hope this helps.
For me the solution was to:
Data > From Text > Choose your csv file
Then you can define all the import settings for csv files.
I found another way to fix this, without changing your windows local settings.
In Excel, you go to File > Options > Advanced.
Un-check the "Use System Separators" within the Editing Options and change the Decimal separator with "," and the Thousands Separator ".".
Even it does look more like a bug than a feature of Excel 2016, it works without changing the Windows Local settings, and it's just a local Excel change.
Just had this same problem. Changing the file extension from csv to txt and opening in Excel brings up the classic wizard so you can map the strings to fields.
The correct answer is to edit your regional settings as suggested above (if a long term change in behavior is desired)
Control Panel -> Region -> Additional Settings -> List separator:
But for my purposes a simple Edit -> Find and Replace using Notepad to replace all commas with semi-colons was a quick and dirty solution that I preferred.
Despite the comment that csv means 'Character Separated Values', in Office 2016 my .csv file association to Excel still says 'Microsoft Excel Comma Separated Values File'.
I have quite a complex csv file where none of the suggestions worked out for me. So I ended up using LibreOffice Calc for the job. It worked like a dream.
I had the same problem, I fixed it in this way (Excel 2020)
Data -> Text to Columns
Now you can configure as you wish the CSV delimiters/endlines...
I had the same issue on Mac OS X El Captain. The answer given here worked for me. Reproducing it here in case the link doesnt work in future:
Close the Excel application
Click on the Apple button
Select System Preferences
Select Language and Region
Click Advanced
Change the Decimal separator from a comma (,) to a full stop (.)
Then click on Ok/Save
Test the Excel import again
When changing the list separator, make sure it doesn't overlap with the decimal symbol and the digit grouping characters. I had to change my list separator to (,) my decimal to (.) end my digit grouping to ('). Now .CSV opens lekker!!!
In my excel, it's: data> get data> from file> from text/csv
Try opening in excel, then using text to columns, based on commas.
You could probably create some simple vba to open it in that way too.

If I opened a csv file, Excel used to automatically format it into columns. At some point in the past Excel just stopped doing this.
I'm using Office 365 Business, Excel version 1803. Windows 10 ver 1709
I want to be able to double click on a csv file and have it open automatically formatted into columns.
This is not machine specific as my coworker has an identical issue on a different brand of computer.
So far I have tried the following:
Changing the list separator: I cannot find the list separator setting in office 365, I think it may have been buried or removed.
The "decimal separator" is a comma.
Creating a simple csv to test with. I tested with this csv and it still has the same problem:
Date,Count
2018-01-02,22
2018-01-03,24
I do know I can use text to columns and write macros to accomplish this. I want to avoid those if possible so I can just open a csv and it's formatted.
Thanks, any insights here would be great. I am really hoping it is some system or excel setting.
I came across this and I hope that 1 year and 10 months later it will still help somebody.
Had the same problem and solved it by "Change date, time or number formats" in the Control Panel.
Standard the Format is "Match Windows display language"
My Windows is in English (list separator = ",") but I live in Belgium where the list separator is ";"
So in formats, I changed the Format to "Dutch (Belgium)". That solved it for me.
Once you change your country, double-check in "Additional Settings" if the separator is what you want. Keep in mind that also other things might change, such as decimal symbol and digit grouping symbol.
If you don't want that, you might only want to change the separator and don't change the country.
Best regards,
Koen

And here is how Excel shows its content:
In another post they say it's due to the usage of the , instead of ;
Is it possible to solve the problem without changing Operating System settings?
You can select column A and go to Data - Text to Columns. Then use delimited and define , as the delimiter. This will delimit the data and show it correctly.
If you're asking how to make it delimit based on the comma when you open it, I didn't read the question that way. But instead of double-clicking the file to open, go to the Data tab and Get External Data from it, defining the delimiter.
I use a trick.
Change the extencion from CSV to TXT, the open the file with excel, define , as the delimitator character
In Excel 2010 and newer csv files are read correctly. In older versions you need to specify a separator during import in text import wizard.
I'm working on a .NET application which exports CSV files to open in Excel and I'm having a problem with preserving leading zeros when the file is opened in Excel. I've used the method mentioned at http://creativyst.com/Doc/Articles/CSV/CSV01.htm#CSVAndExcel
This works great until the user decides to save the CSV file within Excel. If the file is opened again in Excel then the leading zeros are lost.
Is there anything I can do when generating the CSV file to prevent this from happening.
This is not a CSV issue.
This is Excel loving to play with CSV files.
Change the extension to something else.
As #GSerg mentions, this is not a CSV issue.
If your users must edit/save in Excel they need to select the entire worksheet, right-click and choose "Format Cells" and from the Category list select "Text" after opening the csv file. This will preserve the leading zeros since the numbers will be treated as simple text.
Alternatively, you could use Open XML SDK 2.0, or some other Excel library, to create an xlsx file from your csv data and programmaticaly set the Cell type to Text in order to take the end users out of the equation...
I found a nice way around this, if you add a space anywhere along the phone number, the cell is then not treated as number and is treated as a text cell in both Excel and Apple's iWork Numbers.
It's the only solution I've found so far that plays nice with Numbers.
Yes I realise the number then has a space, but this is easy to process out of large chunks of data, you just have to select a column and remove all spaces.
Also, if this is web related, most web type things are ok with users entering a space in the number field. E.g you can tap-to-call on mobiles.
The challenge is to get the space in there in the first place.
In use:
01202123456 = 1202123456
but
01202 123456 = 01202 123456
Ok, new discovery.
Using Quick Preview on Mac to view a CSV file the telephone column will display perfectly, but opening the file fully with Numbers or Excel will ruin that column.
On some level Mac OS X is capable of handling that column correctly with no user meddling.
I am now working on the best/easiest way to make a website output a universally accepted CSV with telephone numbers preserved.
But maybe with that info someone else has an idea on how to make Numbers handle the file in the same way that Quick Preview does?
I'm working on a feature to export search results to a CSV file to be opened in Excel. One of the fields is a free-text field, which may contain line breaks, commas, quotations, etc. In order to counteract this, I have wrapped the field in double quotes (").
However, when I import the data into Excel 2007, set the appropriate delimiter, and set the text qualifier to double quote, the line breaks are still creating new records at the line breaks, where I would expect to see the entire text field in a single cell.
I've also tried replacing CR/LF (\r\n) with just CR (\r), and again with just LF (\n), but no luck.
Has anyone else encountered this behavior, and if so, how did you fix it?
TIA,
-J
EDIT:
Here's a quick file I wrote by hand to duplicate the problem.
ID,Name,Description
"12345","Smith, Joe","Hey.
My name is Joe."
When I import this into Excel 2007, I end up with a header row, and two records. Note that the comma in "Smith, Joe" is being handled properly. It's just the line breaks that are causing problems.
Excel (at least in Office 2007 on XP) can behave differently depending on whether a CSV file is imported by opening it from the File->Open menu or by double-clicking on the file in Explorer.
I have a CSV file that is in UTF-8 encoding and contains newlines in some cells. If I open this file from Excel's File->Open menu, the "import CSV" wizard pops up and the file cannot be correctly imported: the newlines start a new row even when quoted. If I open this file by double-clicking on it in an Explorer window, then it opens correctly without the intervention of the wizard.
None of the suggested solutions worked for me.
What actually works (with any encoding):
Copy/paste the data from the csv-file (open in a text editor), then perform "text to columns" --> data gets transformed incorrectly.
The next stap is to go to the nearest empty column or empty worksheet and copy/paste again (same thing what you already have in your clipboard) --> automagically works now.
If you are doing this manually, download LibreOffice and use LibreOffice Calc to import your CSV. It does a much better job of stuff like this than any version of Excel I've tried, and it can save to XLS or XLSX as required if you need to transfer to Excel afterwards.
But if you're stuck with Excel and need a better fix, there seems to be a way. It seems to be locale dependent (which seems idiotic, in my humble opinion). I don't have Excel 2007, but I have Excel 2010, and the example given:
ID,Name,Description
"12345","Smith, Joe","Hey.
My name is Joe."
doesn't work. I wrote it in Notepad and chose Save as..., and next to the Save button you can choose the encoding. I chose UTF-8 as suggested, but with no luck. Changing the commas to semicolons worked for me, though. I didn't change anything else, and it just worked. So I changed the example to look like this, and chose the UTF-8 encoding when saving in Notepad:
ID;Name;Description
"12345";"Smith, Joe";"Hey.
My name is Joe."
But there's a catch! The only way it works is if you double-click the CSV file to open it in Excel. If I try to import data from text and chose this CSV, then it still fails on quoted newlines.
But there's another catch! The working field separator (comma in the original example, semicolon in my case) seems to depend on the system's Regional Settings (set under Control Panel -> Region and Language). In Norway, comma is the decimal separator. Excel seems to avoid this character and prefer a semicolon instead. I have access to another computer set to UK English locale, and on that computer, the first example with a comma separator works fine (only on doubleclick), and the one with semicolon actually fails! So much for interoperability. If you want to publish this CSV online and users may have Excel, I guess you have to publish both versions and suggest that people check which file gives the correct number of rows.
So all the details that I've been able to gather to get this to work are:
The file must be saved as UTF-8 with a BOM, which is what Notepad does when you chose UTF-8. I tried UTF-8 without BOM (can be switched easily in Notepad++), but then double-clicking the document fails.
You must use a comma or a semicolon separator, but not the one that is the decimal separator in your Regional Settings. Perhaps other characters work, but I don't know which.
You must quote fields that contain a newline with the " character.
I've used Windows line-endings (\r\n) both in the text field and as a record separator, that works.
You must double-click the file to open it, importing data from text doesn't work.
Hope this helps someone.
I have finally found the problem!
It turns out that we were writing the file using Unicode encoding, rather than ASCII or UTF-8. Changing the encoding on the FileStream seems to solve the problem.
Thanks everyone for all your suggestions!
Use Google Sheets and import the CSV file.
Then you can export that to use in Excel
Short Answer
Remove the newline/linefeed characters (\n with Notepad++). Excel will still recognise the carriage return character (\r) to separate records.
Long Answer
As mentioned newline characters are supported inside CSV fields but Excel doesn't always handle them gracefully. I faced a similar issue with a third party CSV that possibly had encoding issues but didn't improve with encoding changes.
What worked for me was removing all newline characters (\n). This has the effect of collapsing fields to a single record assuming that your records are separated by the combination of a carriage return and a newline (CR/LF). Excel will then properly import the file and recognise new records by the carriage return.
Obviously a cleaner solution is to first replace the real newlines (\r\n) with a temporary character combination, replacing the newlines (\n) with your seperating character of choice (e.g. comma in a semicolon file) and then replacing the temporary characters with proper newlines again.
If the field contains a leading space, Excel ignores the double quote as a text qualifier. The solution is to eliminate leading spaces between the comma (field separator) and double-quote. For example:
Broken:
Name,Title,Description
"John", "Mr.", "My detailed description"
Working:
Name,Title,Description
"John","Mr.","My detailed description"
If anyone stumbling across this thread and is looking for a definitive answer here goes (credit to the person mentioning LibreOffice:
1) Install LibreOffice
2) Open Calc and import file
3) My txt file had the fields separated by , and character fields enclosed in "
4) save as ODS file
5) Open ODS file in Excel
6) Save as .xls(x)
7) Done.
8) This worked perfectly for me and saved me BIGTIME!
+1 on J Ashley's comment. I ran into this problem also. It turns out that Excel requires:
A newline character("\n") in the quoted string
A carriage return and newline between each row.
E.g.
"Test", "Multiline item\n
multiline item"\r\n
"Test2", "Multiline item\n
multiline item"\r\n
I used notepad ++ to delimit each row properly and to only use newlines in the string. Discovered this by creating multiline entries in a blank excel doc and opening the csv in notepad ++.
Overview
Almost 10 years after the original post, Excel hasn't improved in importing CSV files. However, I found that it is much better in importing HTML tables. So, one can use Python to convert CSV to HTML and then import the resulting HTML to Excel.
The advantages of this approach are: (a) it works reliably, (b) you don't need to send your data to a third party service (e.g. Google sheets), (c) no extra "fat" installations required (LibreOffice, Numbers etc.) for most users, (d) higher level than meddling with CR/LF characters and BOM markers, (e) no need to fiddle with locale settings.
Steps
The following steps can be run on any bash-like shell as long as Python 3 is installed. Although Python can be used to directly read CSV, csvkit is used to do an intermediate conversion to JSON. This allows us to avoid having to deal with CSV intricacies in our Python code.
First, save the following script as json2html.py. The script reads a JSON file from stdin and dumps it as an HTML table:
#!/usr/bin/env python3
import sys, json, html
if __name__ == '__main__':
header_emitted = False
make_th = lambda s: "<th>%s</th>" % (html.escape(s if s else ""))
make_td = lambda s: "<td>%s</td>" % (html.escape(s if s else ""))
make_tr = lambda l, make_cell: "<tr>%s</tr>" % ( "".join([make_cell(v) for v in l]) )
print("<html><body>\n<table>")
for line in json.load(sys.stdin):
lk, lv = zip(*line.items())
if not header_emitted:
print(make_tr(lk, make_th))
header_emitted = True
print(make_tr(lv, make_td))
print("</table\n</body></html>")
Then, install csvkit in a virtual environment and use csvjson to feed the input file to our script. It is a good idea to disable cell type guessing with the -I argument:
$ virtualenv -p python3 pyenv
$ . ./pyenv/bin/activate
$ pip install csvkit
$ csvjson -I input.csv | python3 json2html.py > output.html
Now output.html can be imported in Excel. Line breaks in cells will have been preserved.
Optionally, you may want to cleanup your Python virtual environment:
$ deactivate
$ rm -rf pyenv
Multiline CSV can be imported easily in Excel versions with Power Query using following steps (tested in Excel 365 version 2207):
Go to Data-tab
Click "From Text/CSV" on the ribbon
Select file and click Import
Click "Transform Data" to open Power Query Editor
Click "Data source settings" on the Power Query Editor ribbon
Click "Change Source"
Select "Ignore quoted line breaks" from the "Line breaks" dropdown.
Click OK -> Close -> Close & Load
Paste into Notepad++, select Encoding > Encode in ANSI, copy all again and paste into Excel :)
I had a similar problem. I had some twitter data in MySQL. The data had Line feed( LF or \n) with in the data. I had a requirement of exporting the MySQL data into excel. The LF was messing up my import of csv file. So I did the following -
1. From MySQL exported to CSV with Record separator as CRLF
2. Opened the data in notepad++
3. Replaced CRLF (\r\n) with some string I am not expecting in the Data. I used ###~###! as replacement of CRLF
4. Replaced LF (\n) with Space
5. Replaced ###~###! with \r\n, so my record separator are back.
6. Saved and then imported into Excel
NOTE- While replacing CRLF or LF dont forget to Check Excended (\n,\r,\t... Checkbox [look at the left hand bottom of the Dialog Box)
My experience with Excel 2010 on WinXP with French regional settings
the separator of your imported csv must correspond to the list separator of your regional settings (; in my case)
you must double click on the file from the explorer. don't open it from Excel
On MacOS try using Numbers
If you have access to Mac OS I have found that the Apple spreadsheet Numbers does a good job of unpicking a complex multi-line CSV file that Excel could not handle. Just open the .csv with Numbers and then export to Excel.
Excel is incredibly broken when dealing with CSVs. LibreOffice does a much better job. So, I found out that:
The file must be encoded in UTF-8 with BOM, so consider this for all the points below
The best result, by far, is achieved by opening it from File Explorer
If you open it from within Excel there are two possible outcomes:
If it has only ASCII characters, it will most likely work
If it has non-ASCII characters, it will mess your line breaks
It seems to be heavily dependent on the decimal separator configured in the
OS's regional settings, so you have to select the right one
I would bet that it may also behave differently depending on OS and
Office version
This is for Excel 2016:
Just had the same problem with line breaks inside a csv file with the Excel Wizard.
Afterwards I was trying it with the "New Query" Feature:
Data -> New Query -> From File -> From CSV -> Choose the File -> Import -> Load
It was working perfectly and a very quick workaround for all of you that have the same problem.
With Excel 2019 I had a similar problem when working with CSV files via Data -> Import from text file / CSV. Once the connection is made and the data is synced, it reported xx error(s) because of shifted columns caused by the line breaks.
I managed to solve this by
Edit the query (Query -> Edit)
This opens the Power Query Editor
Go to Start -> Advanced Editor
This opens the query in text format, where line #2 had an instruction like
Source = Csv.Document(File.Contents("my.csv"),[Delimiter=",", .... , QuoteStyle=QuoteStyle.None]),
Change QuoteStyle.None to QuoteStyle.Csv
Click Finish
Apply & close
Documentation found here: https://learn.microsoft.com/en-us/powerquery-m/csv-document
NB. I since found where this is "hidden" in the UI. In the Power Query-editor, click Data source settings, Change source (bottom left), and the Line breaks combo should say Ignore line breaks between quotes.
NB2. Working from Dutch Excel here so my above-mentioned translations of button captions etc. may be a little off.
What just worked for me, importing into Excel directly provided that the import is done as a text format instead as csv format.
M/
just create a new sheet with cells with linebreak, save it to csv then open it with an editor that can show the end of line characters (like notepad++). By doing that you will notice that a linebreak in a cell is coded with LF while a "real" end of line is code with CR LF. Voilà, now you know how to generate a "correct" csv file for excel.
I also had this problem: ie., csv files (comma delimited, double quote delimited strings) with LF in quoted strings. These were downloaded Square files. I did a data import but instead of importing as text files, imported as "from HTML". This time it ignored the LF's in the quoted strings.
This worked on Mac, using csv and opening the file in Excel.
Using python to write the csv file.
data= '"first line of cell a1\r 2nd line in cell a1\r 3rd line in cell a1","cell b1","1st line in cell c1\r 2nd line in cell c1"\n"first line in cell a2"\n'
file.write(data)
In my case opening CSV in notepad++ and adding SEP="," as the first line allows me open CSV with line breaks and utf-8 in Excel without issues
Replace the separator with TAB(\t) instead of comma(,).
Then open the file in your editor (Notepad etc.), copy the content from there, then paste it in the Excel file.
It appears that this is much easier in more recent versions of Excel:
Go to "Data" -> "Get Data (Power Query)"
In the dialogue that opens, select "Text / CSV" on the right
Search for the file and then click "Next" and follow the recommendations (in my case, Excel now correctly realized it's UTF8 and that cells were separated by ";" and the text identifier were double quotes (")
You're done!
This took a little moment to load but afterwards I had an auto-formatted table that looked really nice and that did understand that multi-line entries were still part of the same entry.
If you want the multi-lines to show correctly, simply format the cells and under "Alignment", click the checkbox for "Wrap text". That should solve the last of your issues.
Good luck! ;-)
I want to generate a CSV file for user to use Excel to open it.
If I want to escape the comma in values, I can write it as "640,480".
If I want to keep the leading zeros, I can use ="001234".
But if I want to keep both comma and leading zeros in the value, writing as ="001,002" will be splitted as two columns. It seems no solution to express the correct data.
Is there any way to express 001, 002 in CSV for Excel?
Kent Fredric's answer contains the solution:
"=""001,002"""
(I'm bothering to post this as a separate answer because it's not clear from Kent's answer that it is a valid Excel solution.)
Put a prefix String on your data:
"N001,002","N002,003"
( As long as that prefix is not an E )
That notation ( In OpenOffice at least) above parses as a total of 2 columns with the N001,002 bytes correctly stored.
CSV Specification says that , is permitted inside quote strings.
Also, A warning from experience: make sure you do this with phone numbers too. Excel will otherwise interpret phone numbers as a floating point number and save them in scientific notation :/ , and 1.800E10 is not a really good phone number.
In OpenOffice, this RawCSV chunk also decodes as expected:
"=""001,002""","=""002,004"""
ie:
$rawdata = '001,002';
$equation = "=\"$rawdata\"";
$escaped = str_replace('"','""',$equation);
$csv_chunk = "\"$escaped\"" ;
Do
"""001,002"""
I found this out by typing "001,002" and then doing save-as CSV in Excel. If this isn't exactly what you want (you don't want quotes), this might be a good way for you to find what you want.
Another option might be use tab-delimited text, if this is an option for you.
A reader of my blog found a solution, ="001" & CHAR(44) & "002", it seems workable on my machine!
Pretty old thread but why don't you just add whitespace after your value. It will be then treated as string and no leading zeros will be stripped.
"001,002"." "
Since no-one mentioned it already, figured it was worth mentioning it in this old post.
If you add a horizontal tab character \t before the number, then MS Excel will also show the leading zero's. And the tab character doesn't show in the excel sheet. Even if it's surrounded by double-quotes. (F.e. \"\t001,002\")
It also looks nicer in Notepad++, compared to putting a \0 aka NULL before such number.
Looking more at the Excel spreadsheet it looks what you want can't be done using CSV.
This site http://office.microsoft.com/en-us/excel/HP052002731033.aspx says "If cells display formulas instead of formula values, the formulas are converted as text. All formatting, graphics, objects, and other worksheet contents are lost. The euro symbol will be converted to a question mark."
However, you can change how you load it to get the result you want. See this web page:
Microsoft import a text file.
The key thing is to choose Import External Data-Import Data-Text Files, go Next, Next, and then tick "Text" under column data format. This will prevent it being interpreted as a number, and losing formatting.
I was fiddling around with CSV to Excel (i use PHP to create the CSV, but i guess this solution works for any language. When you spot that a leading characters (such as + , - or 0 are disappearing, create the CSV with chr(13) as a prefix. This is a non printable character and it works wonders for my Excel Office 2010 version. I tried other non printable characters, but with no luck.
so i use Chirp Internet solution but tweaked with my prefix:
if (preg_match("/^0/", $str) || preg_match("/^\+?\d{8,}$/", $str) || preg_match("/^\d{4}.\d{1,2}.\d{1,2}/", $str)) {
$str = chr(13)."$str";
}
If you are using "Content-Disposition" and exporting from asp to excel using HTML tags,then you have to add "style='mso-number-format:\#;'" to that tag and making it to accept only Text values ,thereby leading zeroes omission will be avoided,If Forward slash"\" is accepted use double forward slash "\"
All the suggested answers don't seem to work for me right now ("=""blahblah""" and others) in all current Excel versions or Numbers app on OS X.
The only solution I found to be working by fiddling around is to add an escaped null character at the beginning of the string (which is \0 in PHP or C based languages). Everything ends up treated as is without being calculated or processed by the software when opening the calc sheet.
echo "\0" . $data;
Excel uses a default formatting for CSV columns depending on the content. So if you have 001 in a csv, excel will automatically turn it to 1.
The only way to keep the leading zeros in excel from a csv file is by changing the extension of the csv file to .txt, then just open excel, click on open, select the txt file, and you'll see the Text Import Wizard. Select your csv format (separated by commas), then just make sure you select "Text" as the format.
And that's it, now you can export that previous csv data to any other while keeping the leading zeros.
