# Making a csv file

Coll.ai supports CSV, or comma-separated values, files at the moment. You can create a .csv file using a simple text editor, but you can also export Microsoft Excel or Google Sheets documents to the format for upload.

See [here](https://support.microsoft.com/en-us/office/import-or-export-text-txt-or-csv-files-5250ac4c-663c-47ce-937b-339e391393ba) and [here](https://www.spreadsheetclass.com/google-sheets-export-csv/) on how to export a CSV file from Excel and Google Sheets, respectively.
