OperationsFour key-level batch operations: bulk rename (whole key / substring), delete keys by name, extract a subtree by dot path, and key-case conversion (camel / snake / kebab / Pascal); rename collisions are flagged.

Why use the JSON Key Batch Tools

Bulk key rename

Whole-key or substring matching across the entire tree — clean prefixes and rename fields without scripts.

Delete by key name

List key names and every match is removed with its subtree — strip debug fields and slim responses in one step.

Extract a subtree

Pull out any subtree by dot path (e.g. items.0.profile) instead of expanding and copying by hand.

Key case conversion

Convert keys between camelCase / snake_case / kebab-case / PascalCase to align backend and frontend conventions.
