Private JSON workflow

One chain for sensitive JSON: format → diff → encode → JWT — entirely in your browser. Bookmark this hub once.

Tool processing runs in your browser — your pastes/files are not uploaded to our servers for processing.Details

  1. 1. Format & validatePretty-print or minify. Fix hints for trailing commas and JSON5-ish mistakes — all local.
  2. 2. Diff two payloadsStructural compare before/after API responses without pasting to a cloud diff site.
  3. 3. Base64 encode (if needed)Encode or decode fragments for headers and tokens — encoding, not encryption.
  4. 4. Decode JWT claimsRead header/payload, flag alg:none, optional HS256 verify — token stays in this tab.
  5. Why private beats cloud pasteWhen secrets, tokens, or production JSON should never leave the device.

Frequently asked questions

Is this safer than paste-to-cloud JSON tools?

Yes for privacy of the payload: formatting, diff, Base64, and JWT decode run in your browser after the page loads. We do not upload your JSON to our servers for processing. Still treat production secrets carefully on a shared machine.

What order should I use?

Start with Format to validate. Use Diff when comparing two versions. Use Base64 or JWT only when the payload needs those steps.
