Convert Excel to CSV
Excel workbooks (.xlsx) carry formulas, formatting, charts and multiple sheets, but most databases, scripts and import tools just want plain rows of values. Converting Excel to CSV flattens the active sheet into comma-separated text that almost any system can read. It runs entirely in your browser, so your spreadsheet never leaves your computer.
Drop your .xlsx below and choose CSV.

Why convert Excel to CSV?
- CSV is the universal import format for databases, CRMs, and data pipelines that reject native .xlsx files.
- Strips Excel-only baggage — formulas become their last calculated values, and formatting, charts, and macros are dropped.
- Plain text stays diff-friendly and easy to version-control or process with command-line tools.
- No upload required: sensitive financials and customer lists are converted locally in your browser.

Frequently asked questions
What happens to my formulas when converting to CSV?+
CSV cannot store formulas, so each cell is exported as its current calculated value. Recalculate everything in Excel before converting so the saved numbers are correct.
Can I convert a workbook with multiple sheets to one CSV?+
CSV is a single flat table, so it can only hold one sheet at a time. Convert each sheet separately, or use the JSON/HTML output if you need to keep several sheets together.
Will my cell formatting and colors survive?+
No. CSV is plain text with no styling — fonts, colors, borders, and number formatting are removed. Only the raw cell values remain.
