Frequently Asked Questions
How do I convert Excel to CSV?
Drop your .xlsx, .xls, or .ods file into TryDocsy's Excel to CSV converter. Pick the sheet you want, choose a delimiter, and the CSV appears instantly — then copy it or download a .csv file.
Can it handle workbooks with multiple sheets?
Yes. Each sheet is listed as a tab; switch between them to preview and download individually, or use “All (.zip)” to export every sheet as separate CSV files in one ZIP.
Which formats can I convert?
Excel .xlsx and legacy .xls, macro-enabled .xlsm, and OpenDocument .ods spreadsheets are all supported. The output is a standard comma-separated CSV (or your chosen delimiter).
Can I change the delimiter?
Yes. Choose comma, semicolon, tab, or pipe. Semicolons are handy for European locales, and tab produces a TSV. Cells containing the delimiter, quotes, or newlines are quoted automatically per RFC 4180.
Is my spreadsheet uploaded to a server?
No. The file is parsed entirely in your browser with a WebAssembly-free JavaScript engine. Your data never leaves your device, so it's safe for confidential spreadsheets.
Does converting change my numbers or dates?
The CSV uses the displayed cell values, so formatted numbers and dates come out as you see them in Excel. Formulas are exported as their computed result.
