What it does

This is the hub for the CSV suite: a growing set of converters and utilities that all run entirely in your browser, so your data is never uploaded.

Pick a tool below to convert CSV to another format, pull CSV out of JSON, XML or HTML, or reshape and clean a file.

Private and unlimited

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.

Preguntes freqüents

Do these tools upload my file?

No. Every tool in the suite runs client-side in your browser. Your CSV never leaves your device, so it is safe for confidential and personal data.

Is there a row or file-size limit?

There is no fixed row cap or daily quota. Because everything runs locally the practical limit is your device's memory, which comfortably handles the tens of thousands of rows most exports contain.

Is my data uploaded anywhere?

No. The conversion runs entirely in your browser with client-side JavaScript, so nothing you paste or drop ever leaves your device. That makes it safe for spreadsheets that contain customer emails, financial figures or other sensitive data.
