About csvquick

Free CSV, Excel and JSON tools that don't upload your files.

Why this exists

Most online CSV tools are built around uploading your data to a server. That's a privacy and security risk — especially when the data contains customer info or financial records. Modern browsers can do all the work locally, with no upload at all.

csvquick is a small collection of tools built that way: every conversion runs in your browser, on your device. No signup, no watermarks, no file-size hostage tactics.
