Csv file length limit

This happens from within Excel File - open or from double clicking the file in explorer. If I try with Ms Access, I get a size warning and it refuses to load the file. At least I get a warning. I would have expected Excel to load at least the first rows If that is what there are in the file , and give an error.

I have confirmed it is Win 7 64bit, Excel 64bit. I am fairly confident we are over the file size but without an error message, I don't know what to tell my client whom is looking to me for answers. I have already discussed that the 89gb file in Excel is unreasonable and they are looking at a stat's package but I need an answer on these smaller files.

I assume that a CSV about 2 Gb or larger will simply not load up into Excel and the fact I get no error message and a new sheet appears is simply an Excel design fault. I beleive it should come up with an error, but does not.

That is why I would like to know what the max size csv file or any file can be, that is opened with Excel.

If I have a figure then I can turn to the client, without having to mess about and prove it, and tell them that is is a fact that the file is too large.

Debits and Credits were not in balance because the value that uploaded into the software was Through experimenting, I found the pinpoint cause of the full value not being uploaded was from just saving the CSV file after copying data into the CSV file from Excel.

That format displays up to 11 characters -- in this case, 10 digits.

When you save to a CSV file, Excel writes the numbers as they are displayed. The remedy: after you open the CSV file, change the cell formats accordingly. In this case, you might want Number with 2 decimal places.

By definition, CSV files lose all formatting information. Instead, you should save to Excel to retain formatting information. Saving to XML might also work if you need to "transfer" Excel data to another application. Of course, the other application must support XML input.

The most common method used by clients currently is for CSV files to be created as dated files by month or week and are backed up before being deleted to ensure they can be recovered later. Keeping these files smaller makes handling and organizing the files easier. It also makes transferring these files between UAT, Test, Development, and Production servers much simpler and quicker. Either way understanding the differences between how these methods work will help to ensure you don't encounter any issues with the size of your CSV files.
