About JSONCraft

JSONCraft is a focused, no-nonsense tool for working with JSON: pretty-printing, minifying, and validating it, searching any key or path, exporting arrays of objects to CSV, and exploring the whole structure in a collapsible tree view. Everything runs entirely in your web browser — no JSON you paste is ever sent to a server.

Because there is no server-side processing or account system, JSONCraft can stay completely free with no sign-up, no watermark, and no usage limits. The site is supported by on-page advertising.

If your JSON is invalid, JSONCraft tells you exactly where it broke — the line and column of the syntax error — so you can fix it fast instead of hunting through a wall of text.

What you can do

  • • Beautify JSON with clean 2-space indentation
  • • Minify JSON to the smallest valid payload
  • • Validate with exact line/column error locations
  • • Search keys, values, or dotted paths and highlight matches
  • • Export an array of objects to a downloadable CSV
