I have an excel file close to 300MB. There are a few tabs and are all text based.
All fonts are the same. Some are characters and some are date formats. one tab is close to 1M row now. But the number of columns in all tabs are only less than 30. No macros included or links to other files.
I read that Excel limit is ~1M rows X 2000 columns. Does that mean as long as my columns are less than 30, then this file can still potentially grow? Or would it just stop running once it reaches 1M?
thanks in advance.
Once you have 2^20 (1048576) rows you will not be able to add a new row. In order to understand this, select range A1 and keep pressing Ctrl+Down arrow until you see the last row. Once you reach it, you cannot go further.
Concerning the 1.000.000+ entries and the need for more rows - it seems that you are using Excel as a database, and it is really not a good idea to use it as one. If you need so many entries, you probably need a nice database, which would be fast and easy. MS Access (as far as you are using Excel, this is the db with most similar interface) can solve your solution easily. Or MS SQL Server.
I have 5 folders and each folder consists of around 20 excel sheets.
And these excel sheets contain duplicates within it. It is becoming very hectic to open every file and remove duplicates.
Is there anyother way to remove duplicates from all these files at once ?
All the files contain different set of duplicates and no common columns will be present.
XD I'm really understanding your situation but I think that the solution will be one of two :) :
1-make a program with any programming language you can use and try to load the files one by one to do what you want
2-(the easiest one)Try to find a good converter to convert all your files to SQL tables then come here to this site and ask how to delete duplicated rows from different SQL tables after doing that reconvert the SQL tables to EXCEL files again and it will be done (y) ;)
I see that the number of rows at a worksheet is limited to 1,048,576.
Is this just an excel thing? For example can I create a csv file that has more rows say 5 Million rows? I understand I can't open it with excel but can I still have the file and access it some other way (say C++).
I assume this is feasible as CSV is not necessarily an excel thing right?
Thanks in advance.
A CSV file is simply a text file formatted in a certain way. Excel's row limitation is simply an artificial limitation. There is no artificial limit to the size of a CSV file.
Excel is most certainly Not the only program that can open or create a CSV file. If you want to create a CSV file with something besides Excel, then you can create as many rows or fields as you wish to.
Part of my job is to pull a report weekly that lists patching information for around 75000 PCs. I have to filter some erroneous data, based on certain criteria, and then summarize this data myself and update it in a separate spreadsheet. I am comfortable with pivot tables / formulas, but it ends up taking a good couple of hours.
Is there a way to import data from a CSV file into a template that already has in place my formulas/settings, etc. if the data has the same columns, but a different amount of rows each time?
If you're confortable with programming, then, you can use macros, on this case, you will connect to your CSV file, then extract the information and put it in the corresponding places on your spreadsheet, on this question you can find most of what you need to start off: macro to Import csv file into an excel non active worksheet.
I have been given a CSV file with more than the MAX Excel can handle, and I really need to be able to see all the data. I understand and have tried the method of "splitting" it, but it doesnt work.
Some background: The CSV file is an Excel CSV file, and the person who gave the file has said there are about 2m rows of data.
When I import it into Excel, I get data up to row 1,048,576, then re-import it in a new tab starting at row 1,048,577 in the data, but it only gives me one row, and I know for a fact that there should be more (not only because of the fact that "the person" said there are more than 2 million, but because of the information in the last few sets of rows)
I thought that maybe the reason for this happening is because I have been provided the CSV file as an Excel CSV file, and so all the information past 1,048,576 is lost (?).
DO I need to ask for a file in an SQL database format?
You should try delimit it can open up to 2 billion rows and 2 million columns very quickly has a free 15 day trial too. Does the job for me!
I would suggest to load the .CSV file in MS-Access.
With MS-Excel you can then create a data connection to this source (without actual loading the records in a worksheet) and create a connected pivot table. You then can have virtually unlimited number of lines in your table (depending on processor and memory: I have now 15 mln lines with 3 Gb Memory).
Additional advantage is that you can now create an aggregate view in MS-Access. In this way you can create overviews from hundreds of millions of lines and then view them in MS-Excel (beware of the 2Gb limitation of NTFS files in 32 bits OS).
Excel 2007+ is limited to somewhat over 1 million rows ( 2^20 to be precise), so it will never load your 2M line file. I think that the technique you refer to as splitting is the built-in thing Excel has, but afaik that only works for width problems, not for length problems.
The really easiest way I see right away is to use some file splitting tool - there's tons of 'em and use that to load the resulting partial csv files into multiple worksheets.
ps: "excel csv files" don't exist, there are only files produced by Excel that use one of the formats commonly referred to as csv files...
You can use PowerPivot to work with files of up to 2GB, which will be enough for your needs.
First you want to change the file format from csv to txt. That is simple to do, just edit the file name and change csv to txt. (Windows will give you warning about possibly corrupting the data, but it is fine, just click ok). Then make a copy of the txt file so that now you have two files both with 2 millions rows of data. Then open up the first txt file and delete the second million rows and save the file. Then open the second txt file and delete the first million rows and save the file. Now change the two files back to csv the same way you changed them to txt originally.
I'm surprised no one mentioned Microsoft Query. You can simply request data from the large CSV file as you need it by querying only that which you need. (Querying is setup like how you filter a table in Excel)
Better yet, if one is open to installing the Power Query add-in, it's super simple and quick. Note: Power Query is an add-in for 2010 and 2013 but comes with 2016.
If you have Matlab, you can open large CSV (or TXT) files via its import facility. The tool gives you various import format options including tables, column vectors, numeric matrix, etc. However, with Matlab being an interpreter package, it does take its own time to import such a large file and I was able to import one with more than 2 million rows in about 10 minutes.
The tool is accessible via Matlab's Home tab by clicking on the "Import Data" button. An example image of a large file upload is shown below:
Once imported, the data appears on the right-hand-side Workspace, which can then be double-clicked in an Excel-like format and even be plotted in different formats.
I was able to edit a large 17GB csv file in Sublime Text without issue (line numbering makes it a lot easier to keep track of manual splitting), and then dump it into Excel in chunks smaller than 1,048,576 lines. Simple and quite quick - less faffy than researching into, installing and learning bespoke solutions. Quick and dirty, but it works.
Try PowerPivot from Microsoft. Here you can find a step by step tutorial. It worked for my 4M+ rows!
"DO I need to ask for a file in an SQL database format?" YES!!!
Use a database, is the best option for this problem.
Excel 2010 specifications .
Use MS Access. I have a file of 2,673,404 records. It will not open in notepad++ and excel will not load more than 1,048,576 records. It is tab delimited since I exported the data from a mysql database and I need it in csv format. So I imported it into Access. Change the file extension to .txt so MS Access will take you through the import wizard.
MS Access will link to your file so for the database to stay intact keep the csv file
The best way to handle this (with ease and no additional software) is with Excel - but using Powerpivot (which has MSFT Power Query embedded). Simply create a new Power Pivot data model that attaches to your large csv or text file. You will then be able to import multi-million rows into memory using the embedded X-Velocity (in-memory compression) engine. The Excel sheet limit is not applicable - as the X-Velocity engine puts everything up in RAM in compressed form. I have loaded 15 million rows and filtered at will using this technique. Hope this helps someone... - Jaycee
I found this subject researching.
There is a way to copy all this data to an Excel Datasheet.
(I have this problem before with a 50 million line CSV file)
If there is any format, additional code could be included.
Try this.
Sub ReadCSVFiles()
Dim i, j As Double
Dim UserFileName As String
Dim strTextLine As String
Dim iFile As Integer: iFile = FreeFile
UserFileName = Application.GetOpenFilename
Open UserFileName For Input As #iFile
i = 1
j = 1
Check = False
Do Until EOF(1)
Line Input #1, strTextLine
If i >= 1048576 Then
i = 1
j = j + 1
Else
Sheets(1).Cells(i, j) = strTextLine
i = i + 1
End If
Loop
Close #iFile
End Sub
You can try to download and install TheGun Text Editor. Which can help you to open large csv file easily.

Split the CSV into two files in Notepad. It's a pain, but you can just edit each of them individually in Excel after that.
