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?

Can Excel interpret the URLs in my CSV as hyperlinks? If so, how?
You can actually do this and have Excel show a clickable link. Use this format in the CSV file:
=HYPERLINK("URL")
So the CSV would look like:
1,23.4,=HYPERLINK("http://www.google.com")
However, I'm trying to get some links with commas in them to work properly and it doesn't look like there's a way to escape them and still have Excel make the link clickable.
Does anyone know how?
With embedding the hyperlink function you need to watch the quotes. Below is an example of a CSV file created that lists an error and a link to view the documentation on the method that failed. (Bit esoteric but that's what I am working on)
"Details","Failing Method (click to view)"
"Method failed","=HYPERLINK(""http://some_url_with_documentation"",""Method_name"")"
I read all of these answers and some others but it still took a while to work it out in Excel 2014.
The result in the csv should look like this
"=HYPERLINK(""http://www.Google.com"",""Google"")"
Note: If you are trying to set this from MSSQL server then
'"=HYPERLINK(""http://www.' + baseurl + '.com"",""' + baseurl + '"")"' AS url
you can URL Encode your commas inside the URL so the URL is not split across multiple cells.
Just replace commas with %2c
http://www.xyz.com/file,comma.pdf
becomes
=hyperlink("http://www.xyz.com/file%2ccomma.pdf")
Yes, but it's not possible to link them automatically. CSV files are just text files - whatever opens and reads them is responsible for allowing you to click the link.
As to how Excel seems to handle CSV files - everything between commas is interpreted as if it already had been typed into the cell. Therefore, the CSV file containing ="http://google.com",=A1 will display as http://google.com,http://google.com in Excel. It's important to note, however, that hyperlinks in Excel are metadata, and not the result of anything in the actual cell (ie, a hyperlinked cell to Google still contains http://google.com not <a>http://google.com</a> or anything of that sort.)
Since that's the case, and all metadata is lost when converting to a CSV, it's impossible to tell Excel you wish for something to be hyperlinked merely by changing the cell value. Normally, Excel interprets your input when you hit 'Enter' and links URLs then, but since CSV data is not being entered, but rather already exists, this does not happen.
Your best bet is to write some sort of addon or macro to run when you open up a CSV which parses every cell and hyperlinks them if they match a URL format.
Use this format:
=HYPERLINK(""<URL>"";""<LABEL>"")
e.g.:
=HYPERLINK(""http://stackoverflow.com"";""I love stackoverflow!"")
P.S. The same format works in LibreOffice Calc as well.
"=HYPERLINK(\"\" " + "http://www.mywebsite.com"+ "\"\")"
use this format before writing to CSV.
As described above, "=HYPERLINK(""http://www.google.com"", ""Google"")" is what worked for me.
However, In Excel Version 2204 Click to Run, I couldn't have leading white space.
For example;
FirstName, "=HYPERLINK(""http://www.google.com"", ""Google"")" fails
FirstName,"=HYPERLINK(""http://www.google.com"", ""Google"")" success
The issue here for me was that because a .CSV by it's nature is Comma separated, any commas in the text file are interpreted as separators. It worked for me by using tab characters as separators, saving it as a .TXT file so that when opened in EXCEL you choose the TAB character rather than ','.
In the text file …
## ensure that the file is TAB separated
Item 1 A file Name data.txt
Item 2 Col 2 =HYPERLINK("http:\www.ilexuk.com","ILEX")
"ILEX" then is shown in the cell and "http:\www.ilexuk.com" is the hyperlink for the cell.
The first few lines of my CSV file look like this (when viewed from Notepad++):
Trace,Original Serial Number,New Serial number
0000073800000000097612345678901234567890,0054,0001
When I open this file in excel, I get this:
For some reason, excel is truncating the serial numbers and the trace number. I have tried changing the format to Text but that still doesn't work, as excel only sees the value up to the 6:
7.38000000000976E+34
If I change it to Number:
73800000000097600000000000000000000.00
What can I do? I only have 60 lines, so if I have to start over and some how recopy the text into excel I will, but I'm afraid saving it will change the format once again.
You shouldn't need to start over or alter the existing CSV. The fastest way might be to use Excel's text import wizard. In the data tab under Get External Data click From Text and select your CSV file.
The wizard that appears will let you tell Excel the data type of each "column" and you can tell it to use text for your barcode.
Excel is trying to "help" you by formatting the input values. To avoid this, do not double-click the file to open it. Instead, open the Data tab and in the Get External Data section, click on From Text
Then tell the Import Wizard that the fields are Text:
One solution that may work for you depending on the environment you consume the csv, you can add a nonnumeric character to the beginning and end (e.g. a "_") of the values. This will force Excel to recognize it as text. You can then remove the "_"s in your downstream environment (SQL, Databricks, etc.) or even keep them if they don't interfere with your reporting.
Funny thing when I want to save Excel columns with long numbers like below, resulting csv contains converted numbers to scientific notation which is unusable. I want them to be save as text. Any trick to do that?
28160010390002003505456159
12160010390002003505456156
39160010390002003505456155
39160010390002003505456155
Append a TAB char (ASCII 9) at the end of a number.
In order to have those long (>15 digit) numbers in Excel, they are already formatted as text. I suspect that the .csv file also shows them as long numbers (if you open the csv file with Notepad), but that when you open the csv file in Excel, you see them as truncated and converted to scientific notation.
If that is the case, what you need to do is IMPORT the csv file. When you do that, the text-to-columns wizard will open, and allow you to format that column as text. The location of the Import is different in different versions. In Excel 2007, it is on the Data ribbon, Get External Data / From Text.
put the number as a function like below:
="123456789123456789"
If, as the original question seems to imply, you are actually:
already working with data in Excel, and
want to save to a CSV format without losing digits in an extra long number,
Then, before doing a 'Save As' to your CSV format, try formatting the column with a custom format, and in the box for the pattern just type #. This will force Excel to see it as a number, however many digits long, without trying to do something else with it like 4.52364E+14 when you actually save it to CSV.
At least, that is how it works for me in Excel 365 at this point in time.
If you are trying to get data into Excel from a CSV, then the answer about using the data import wizard is probably the safest bet instead.
This is an old question, but since at the moment it's still the top result on a google search for the topic, I think the thread should be kept current. Hussein mahyoub provided the only real answer to the question, yet has not gotten the up-votes.
The answer which tells us to add a tab character after your number gets you an string of text with a tab after it inside excel. It looks visually correct, but, it's not correct inside the spreadsheet. If the intent is to use the data in excel as excel data and use formula etc, it could cause problems. Interestingly if you put the tab before the text, it shows up in the data after the text.
The answer which tells us inserting a ' before the text gets a ' in the excel file. It's visually an incorrect representation of the data.
The answer which boasts the virtue of openoffice is simply an evil troll which does not even attempt to answer the question.
The answer that explains how to import a CSV that has not been properly formatted is good information, but, off topic.
The direct answer to the question is
converted to text,largest number
="123456789012",12345678901
Convert the numeric to text using text function.
Text(number,"0")
using openoffice you can save in csv format without problems.
Don't use Export to csv feature in Excel.
You can easy format that column to number in Excel, then use "Save as" it with csv and "yes" to confirm that you want to keep the format in csv.
That is work for me
Click on the column that has scientific exponent number and go to Format cells and then Numbers (decimal point as 0), save it as MSDOS CSV. Worked for me.
The format of our member numbers has changed several times over the years, such that 00008, 9538, 746, 0746, 00746, 100125, and various other permutations are valid, unique and need to be retained. Exporting from our database into the custom Excel template needed for a mass update strips the leading zeros, such that 00746 and 0746 are all truncated to 746.
Inserting the apostrophe trick, or formatting as text, does not work in our case, since the data seems to be already altered by the time we open it in Excel. Formatting as zip won't work since we have valid numbers less than five digits in length that cannot have zeros added to them. And I am not having any luck with "custom" formatting as that seems to require either adding the same number of leading zeros to a number, or adding enough zeros to every number to make them all the same length.
Any clues? I wish there was some way to set Excel to just take what it's given and leave it alone, but that does not seem to be the case! I would appreciate any suggestions or advice. Thank you all very much in advance!
UPDATE - thanks everybody for your help! Here are some more specifics. We are using a 3rd party membership management app -- we cannot access the database directly, we need to use their "query builder" tool to get the data we want to mass update. Then we export using their "template" format, which is called XLSX but there must be something going on behind the scenes, because if we try to import a regular old Excel, we get an error. Only their template works.
The data is formatted okay in the database, because all of the numbers show correctly in the web-based management tool. Also, if I export to CSV, save it as a .txt and import it into Excel, the numbers show fine.
What I have done is similar to ooo's explanation below -- I exported the template with the incorrect numbers, then exported as CSV/txt, and copied / pasted THOSE numbers into the template and re-imported. I did not get an error, which is something I guess, but I will not be able to find out if it was successful until after midnight! :-(
Assuming the data is not corrupt in the database, then try and export from the database to a csv or text file.
The following can then be done to ensure the import is formatted correctly
Text file with comma delimiter:
In Excel Data/From text and selected Delimited, then next
In step 3 of the import wizard. For each column/field you want as text, highlight the column and select Text
The data should then be placed as text and retain leading zeros.
Again, all of this assumes the database contains non-corrupt data and you are able to export a simple text or csv file. It also assumes you have Excel 2010 but it can be done with minor variation across all versions.
Hopefully, #ooo's answer works for you. I'm providing another answer mainly for informational purposes, and don't feel like dealing with the constraints on comments.
One thing to understand is that Excel is very aggressive about treating "numeric-looking" data as actual numbers. If you were to open the CSV by double-clicking and letting Excel do its thing (rather than using ooo's careful procedure), those numbers would still have come up as numbers (no leading zeros). As you've found, one way to counteract this is to append clearly nonnumeric characters onto your data (before Excel gets its grubby hands on it), to really convince Excel that what it's dealing with is text.
Now, if the thing that uploads to their software is a file ending in .xlsx, then most likely it is the current Excel format (a compressed XML document, used by Excel 2007 and later). I suppose by "regular old Excel" you mean .xls (which still works with the newer Excels in "compatibility mode").
So in case what you've tried so far doesn't work, there are still avenues to explore before resorting to appending characters to the end of your data. (I'll update this answer as needed.)
You're on the right track with the apostrophe.
You'll need to store your numbers in excel as text at the time they are added to the file.
What are you using to create the original excel file / export from database?
This will likely be where your focus needs to be regarding your export.
For example one approach is that you could potentially modify the database export to include the ' symbol prefix before the numbers so that excel will know to display them as text.
I use the formula =text(cell,"# of zeros of the field") to add preceding zeros.
Example, Cell C2 has 12345 and I need it to be 10 characters long. I would put =text(c2,"0000000000").
The result will be 0000012345.
Is this at all possible?
If I open up my file in standard text editor e.g. notepad the preceeding zeros are displayed.
e.g. 000485001 shows up.
Although this doesn't happen in excel. All that's displayed is 485001
Just wondering if there's a way around this?
Thanks,
Yes, when you're importing (or using 'Text to columns') you can explicitly indicate the data type for a column (instead of General). If you select 'Text' the zeros will not be dropped.
Unfortunately you only see the dialog to specify this option when Excel is already open and you use either File/Open or Data/Text to Columns. If you just double click a .csv in the explorer you don't get this choice.
Excel tries very hard to determine the type of value it's importing. If it looks like a number, it will treat it like a number, and drop all the leading zeros as it reads it in. There's no way to get them back once they're lost.
You might try to import the file using the wizard that lets you set the data type for each column.
Rather than writing your data as a CSV file, use the SYLK (Symbolic Link) format instead. This format includes information about the style of a column, so that Excel will not try to auto-guess the type of data.
The easiest way to get started with this format is to export a small file from Excel and use that as a template.
Ok got around this by inserting a text character before the number i.e. #000485001
Simple enough!
