About Rename JSON Keys
Rename Keys renames a key wherever it appears in the JSON — including inside nested objects and arrays — in a single step.
It is useful when adapting data to a new schema, renaming API fields, or tidying inconsistent data. Enter the old key and the new key.
The replacement is recursive and thorough. Processed in the browser without sending data anywhere.
FAQ
Is my data sent to a server?
No. Rename JSON Keys runs entirely in your browser using client-side libraries. Your data never leaves your device.
