Frequently Asked Questions

Yes. Every format, minify, validation, search, and CSV export runs on your own device, so there is no server cost per use and no reason to charge or limit usage.

No. Everything is processed locally in your browser using JavaScript. Your data never leaves your device.

It uses the browser's own JSON parser and translates the raw error into a friendly line and column number, so you know exactly where the JSON broke.

Format (Beautify) pretty-prints your JSON with 2-space indentation for readability. Minify strips all unnecessary whitespace to produce the smallest possible output.

Paste a JSON array of flat objects, for example [{"name":"Ada","age":36},{"name":"Alan","age":41}], and click Export CSV. JSONCraft builds a header row from the union of all keys, quotes cells that need it, and downloads a .csv file. Non-array JSON, or arrays that are not objects, cannot be flattened to a table and will show a clear message.

Type any key name, a value, or a dotted path like users.0.email into the search box under the tree view. Every matching node is highlighted, and its parent objects are expanded automatically so the match is visible.

The tree view renders your parsed JSON as a collapsible outline, so you can expand or collapse individual objects and arrays to explore large or deeply nested structures without scrolling through raw text.

There's no artificial limit, but very large JSON payloads are bound by your browser's own memory and rendering performance rather than any restriction JSONCraft imposes.
