JSON / CSV
Convert JSON ↔ CSV
JSON / CSV: Convert JSON ↔ CSV. A free, browser-based tool from DevToolbox that runs entirely on your own device: no upload, no account, no tracking.
About the JSON / CSV
Free online JSON to CSV converter. Convert between JSON and CSV formats instantly. Download results as CSV or JSON files. It is one of the encoders & converters tools on DevToolbox, and like all of them it runs entirely in your browser.
Conversion is a two-step trip: your input is decoded from the source format into a plain in-memory value, then re-encoded into the target format. Round-tripping a value through both directions returns what you started with, apart from formatting that the target format cannot express.

How to use it

- The converted result appears immediately in the output pane.
- Use Copy to take the result, or pipe it into another tool from the workspace.
Questions
- Is my data uploaded anywhere?
- No. The tool is JavaScript that runs in the tab you already have open, and DevToolbox has no backend to send anything to. You can open the network tab and watch: after the page and its script load, nothing is sent while you work.
- Does it work offline?
- Once the page has loaded, yes. The tool needs no network access to do its job, so it keeps working if your connection drops. Reloading the page does need the network unless your browser has it cached.
- Is it free, and do I need an account?
- It is free and there is no account, no sign-in and no usage limit. There is nothing to register because there is no server keeping track of anything.
