About this tool

JSON Convertor & Editor is a free online tool for working with JSON. You can format it, validate it, fix it when it breaks, convert it to other formats, and query it, all from a single page that runs in your browser.

Why we built it

Most people end up with a pile of bookmarks for JSON work: one site to pretty-print, another to convert to CSV, a third to check for errors, and yet another to turn a sample into TypeScript. We wanted one place that does all of it, loads fast, and does not ask you to sign up first.

It also runs on your own device. The JSON you paste is handled by your browser and is not sent to a server, so it stays with you and the tool feels instant even on big files.

What you can do here

• Format, minify, and repair messy or broken JSON.
• Read your data as text, as a collapsible tree, or as a sortable table.
• Convert JSON to CSV, YAML, XML, and query strings, and import those formats back to JSON.
• Generate TypeScript, Go, Python, and JSON Schema from a sample.
• Query and filter with JSONPath, and compare two documents side by side.
