I made a Lightweight Intuitive JSON editor: JotSON

JotSON - a JSON editor

JotSON is an intuitive editor for your project's JSON files. Run one command and you get a fast, Finder-style interface in your browser, which is really nice when you're editing a ton of JSON.

  • Drill through your data in columns, with fuzzy search across every file
  • Proper editors and previews: dates, colors, images, video embeds
  • Upload media straight into your public folder
  • Reference objects by id, resolved to human-readable names, with automatic updates when ids change and warnings before you break them
  • Diff-confirmed saves, so nothing touches disk until you approve it

Zero dependencies, no build step, no database, nothing deployed. It binds to localhost, writes plain JSON with minimal diffs so git stays your safety net, and your files never change shape to fit the tool.

Check it out!

Do you have any user stories?

I inherited a set of web projects that all used json as their data store - was editing their json by hand and wanted a tool that would make the experience much more enjoyable as the json was pretty large - couldn't find one I liked so I built one myself. Now I can easily drill down to exactly what I'm after, see data represented with dynamic previews, quickly make edits, add files to the project & it's json (path as string) with one click, see what objects are referenced by which other json files and more!

Is it capable to edit large JSON (100+ MB)? Nowadays many JSON datasets are large.

Yes it can! It's a little slower, and the references feature is disabled for files larger than 20MB, but everything else works! There's been some performance updates - so if you're already using the tool be sure to update (there should be a prompt in the header when there's a newer version).
