Frequently Asked Questions
Everything you need to know about converting Excel to CSV
Converting Excel to CSV is quick:
- Drag and drop your .xlsx file, or click to browse
- If the workbook has multiple sheets, pick the one you want
- Choose a delimiter, then copy or download the CSV
Everything happens locally in your browser.
Yes. Every worksheet is read, and a dropdown lets you choose which one to export — a CSV file holds a single table, so you pick the sheet you need.
You can — but this tool is handy when:
- You don't have Excel installed (Chromebook, locked-down machine)
- You want a specific sheet, not just the active one
- You want to choose the delimiter yourself
Formula cells export their calculated result, not the formula text. Dates are written in clean ISO format (YYYY-MM-DD) so they import reliably rather than as a serial number.
It reads the modern .xlsx format. For a legacy .xls file, open it in Excel or Google Sheets and re-save it as .xlsx first.
No. The file is read entirely in your browser — nothing is uploaded or stored, so it's safe for sensitive spreadsheets. See our Privacy Policy.
Yes — comma, semicolon, or tab. Cells with the delimiter, quotes, or line breaks are quoted and escaped automatically so the CSV stays valid.
Yes — completely free, with no registration, no limits, and no paywalled features.

From Excel Workbooks to Portable CSV
Why Convert Excel to CSV at All
CSV is the lowest common denominator for tabular data. Databases, programming languages, analytics platforms, and import tools all accept it, while .xlsx is a proprietary, zipped format that many systems can't read directly. Converting to CSV makes your data portable.
The 'Save As' Friction
Excel's own export only saves the active sheet, uses whatever delimiter your system locale dictates, and requires Excel to be installed and open. On a Chromebook or a locked-down work laptop, even that isn't an option.
Drop the File, Get CSV
Drag in an .xlsx file and the converter reads every worksheet in your browser. Pick the sheet you want, choose a delimiter, and copy or download clean CSV — formula results and dates handled correctly, no software required.
Where It Helps
Importing a spreadsheet into a database or CRM, feeding data to a script, sharing a single tab from a big workbook, or preparing a file for a tool that only accepts CSV — all without opening Excel.
Private by Design
Because the workbook is parsed locally in your browser, you can convert financial models, customer lists, or internal reports to CSV without the file ever reaching a server.
