Frequently asked questions

Open this page, paste your Excel text or drop your .xlsx file into the input panel, keep the dropdown set to Excel on the left and CSV on the right, then click Convert. The .csv output appears on the right; copy it to your clipboard or download the file.
Is this Excel-to-CSV converter free?
Yes, completely free. No signup, no watermark, no upload limits. The conversion runs entirely in your browser using open-source libraries.
Does my file get uploaded anywhere?
No. The converter is fully client-side — your Excel file is parsed by JavaScript running in your own browser tab and never leaves your computer. We have no server-side processing for these tools.
What's the difference between Excel and CSV?
Excel (XLSX) is Microsoft's spreadsheet format. It carries the same tabular data as CSV but preserves column formatting and opens directly in Excel. CSV is a flat spreadsheet format. It strips geometry down to lat/lng columns and is the universal way to move place data between tools.
Can I convert CSV back to Excel?
Yes — switch the dropdowns or open our /tools/csv-to-excel/ page. We support every directional pair between KML, GPX, GeoJSON, CSV, and Excel.
