Why use this tool?
Process convert excel to csv should be a 10-second job, not a 10-minute one. Most desktop apps want an installation, ask for an email, or stamp a watermark on the result. This tool does none of that — open the page, upload, get your .csv, move on.
It runs from your browser, so you don't need to trust an unknown program with your files. The actual processing happens on our servers under a tight retention policy: files are auto-deleted within 24 hours and we never read, share, or train models on them.
