How does the JSON Key Removal Tool filter nested objects?

You enter one or more key names (comma-separated). The recursive parsing engine walks the entire JSON structure and removes matching keys at all hierarchy levels.

Can I extract all values from a JSON payload?

Yes. You can toggle between key removal mode and Extract All Values mode to extract flat lists of values such as IDs, email addresses, or names.

Does the tool validate JSON syntax before processing?

Yes. The built-in JSON parser checks for valid syntax and provides helpful error indicators if your input contains broken brackets, trailing commas, or quotes.

Is my sensitive JSON payload uploaded to a server?

No. All JSON manipulation executes locally in your browser. API tokens, user records, and database dumps remain completely private and secure.
