CSV to Excel — Turn a CSV Into a Workbook
Got a raw CSV export that's awkward to read? Convert it into a proper Excel (.xlsx) workbook — with the right delimiter — so you can format, filter, and chart it.
How to convert CSV to Excel
- Upload your .csv file (drag & drop or browse).
- Choose CSV → XLSX and select the delimiter (comma, semicolon, tab, or pipe).
- Download the .xlsx workbook. Your upload is deleted from our server automatically.
Why use File Forge?
- Handles tricky delimiters: European semicolons, tabs, and pipes — not just commas.
- Real workbook output: a native .xlsx you can style and add formulas to.
- Free & verifiably private: deleted after download, open source, no signup.
How File Forge keeps your CSV to XLSX files private
When you use the CSV to XLSX tool, your file is uploaded over an encrypted HTTPS connection and processed on the server, then handed straight back to you. File Forge is built privacy-first, and — because the entire codebase is open source — every claim on this page is something you can verify line by line or run yourself, rather than a marketing promise you have to take on trust.
Your file is deleted the moment you are done
The file you upload is removed from our server as soon as the CSV to XLSX operation finishes, and the processed result is deleted the instant you download it. As a safety net, a background sweeper runs continuously and purges anything older than one hour, so nothing of yours lingers on disk. We never build a library of your documents, never resell them, and never train anything on them. There is no hidden retention and no analytics tied to your file contents.
Open source you can audit — or self-host
Most “free” online file tools ask you to trust a closed black box. File Forge is different: the complete source code is public on GitHub, so a developer can read exactly how the CSV to XLSX tool handles uploads, confirm the deletion logic, and even run a private copy on their own machine or server. Verifiable privacy beats a privacy policy you simply have to believe.
No account, no watermark, no upsell
There is no signup, no email wall, and no credit card. File Forge never stamps a watermark on your output and never caps you at “one free file” before demanding payment. The CSV to XLSX tool is genuinely free to use as often as you need, on any device with a web browser — no software to install and no extensions to add.
