Free JSON Key Filter

⏱️ Estimated read: 1 min | |

Filtering JSON keys by hand is painful.

You lose track of nested objects. You break the structure. You accidentally delete a key you actually needed.

I built a free tool that solves this.

What it does:

  • Filters and extracts specific keys
  • Works across deeply nested JSON
  • Previews the result instantly

Use cases:

  • Removing sensitive data before logging
  • Extracting only needed fields for an API
  • Shrinking massive JSON payloads
  • Cleaning up complex nested objects

Privacy:
100% client-side. Nothing uploaded.
