Free JS Object Key Renamer

ByKandZ

Renaming keys in nested JSON by hand is a nightmare.

One wrong key and your entire data structure breaks. You miss a nested object. The values don’t map.

I built a free tool that solves this.

What it does:

  • Finds and maps specific object keys
  • Batch-renames across nested structures
  • Preserves values and hierarchy

Use cases:

  • Renaming API fields to match your schema
  • Converting snake_case to camelCase
  • Refactoring data structures
  • Standardizing key names across projects

Privacy:
100% client-side. Nothing uploaded.
