Free JSON Flatten & Unflatten Tool

ByKandZ

Nested JSON is painful to work with.

You need dot-notation for a database. You need to rebuild it back. Every time.

I built a free tool that solves this.

What it does:

  • Flattens nested JSON into dot-notation paths
  • Unflattens key-value paths back into objects
  • Works both directions instantly

Use cases:

  • Preparing JSON for database storage
  • Converting to environment variables
  • Form field name mapping
  • Rebuilding nested structures from flat data

Privacy:
100% client-side. Nothing uploaded.
