Can I rename keys in nested objects?

Yes, the tool processes nested structures. You can specify the 'Maximum Depth' to control how deep into the object the renaming logic should reach.

What happens if two keys result in the same name after renaming?

You can configure the 'Handle Naming Conflicts' option to either throw an error, skip the renaming, append a suffix number, or override the existing key.

Does this tool support regex for renaming?

Yes, by selecting 'Pattern Matching' in the Rename Mode, you can use regular expressions to identify and replace key patterns.

Can I convert all keys to camelCase or snake_case automatically?

Yes, the 'Case Conversion' option allows you to automatically transform all keys to formats like camelCase, snake_case, PascalCase, or UPPER_CASE.

Does it work with JSON arrays?

Yes, by enabling the 'Include Array Object Elements' option, the tool will apply your renaming rules to objects contained within arrays.
