File Type:	Comma Separated Values File

The CSV file is a comma separated values file commonly used by spreadsheet programs. CSV contains plain text data sets separated by commas with each new line. The files are often opened by spreadsheet programs to be organized into cells or used for transferring data between databases. It's also helpful for transferring data saved in a proprietary format, such as a .XLSX file, into another program that does not support the XLSX format.

CSV File Complications

Frequent CSV Opening Issues

Microsoft Excel Removed

You attempt to load your CSV file and get an error such as "%%os%% Can't Open The CSV File Extension". Usually, this is because you do not have Microsoft Excel for %%os%% installed. This will prevent you from double-clicking to open the CSV file because the OS doesn’t know how to handle it.

Tip: When you have another program installed that you know will open your CSV, you can select it from the other programs listed (see "Show Apps").

Incorrect Microsoft Excel Version

Your Comma Separated Values File file is incompatible with Microsoft Excel because you might have the wrong version installed. Installing the latest version of Microsoft Excel from Microsoft Corporation is recommended. This problem is predominately due to having a Comma Separated Values File file version that was created by a newer version of Microsoft Excel than what you have installed on your PC.

Tip: Right-clicking on your CSV, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Conclusion: The majority of CSV file opening issues are due to not having the correct Microsoft Excel version installed.

Associated Difficulties Loading CSV Files

Although you might already have Microsoft Excel or another CSV-associated software installed on your computer, you can still encounter problems opening Comma Separated Values File files. If you are continuing to have errors with loading CSV files, other external issues might be to blame. Other contributing causes:

• CSV file references in the Windows Registry are broken
• Unintentional removal of the description of the CSV file inside the Windows Registry
• Defective install of a CSV program, such as Microsoft Excel
• File corruption affecting your CSV file
• CSV file integrity has been compromised by malware
• Device drivers of the hardware associated with your CSV file are corrupt or out-of-date
• Your PC doesn’t have enough available resources to open the Comma Separated Values File file
