JSON Remove Keys – Delete JSON Properties Online
Remove specified keys from JSON objects recursively with a single click. Our free JSON Remove Keys Tool is perfect for sanitizing API responses and stripping sensitive fields.
About JSON Remove Keys
You have a JSON response with fields you don't need. Maybe it's API data with internal IDs, debug info, or sensitive fields you want to strip before logging. Pasting into a text editor and manually deleting properties gets messy fast, especially with nested structures. This tool removes specified keys from your JSON while keeping everything else intact.
How to use this tool
- Paste your JSON object into the input field
- Add the key names you want to remove (one per line)
- Toggle recursive mode if you need to delete nested keys
- Click Remove and get clean JSON output
What makes this useful
The recursive option deletes matching keys at any depth. Turn it on and the tool searches through all nested levels, removing every instance of keys like "password" or "token" wherever they hide.
Multiple key removal means you don't repeat the process. Add all the keys you want gone and hit remove once.
Your original JSON stays in the input field. If you need to start over or try different keys, just clear the key list and run again.
Common questions
Can this remove keys from nested objects?
Yes, enable the recursive checkbox and the tool finds matching keys at any nesting level. You don't need to specify full paths.
What if I enter a key that doesn't exist?
Nothing breaks. The tool skips non-existent keys and removes only what's found. No errors for missing keys.
Does this work on arrays of objects?
Yes. If your JSON contains an array of objects, recursive mode iterates through each object and removes matching keys from all of them.
Can I remove array items by index?
This tool removes object properties by key name, not array elements. For filtering array items, try the JSON Filter tool instead.
Is there a size limit?
The tool runs in your browser with no server limits. Very large files may slow down depending on your available memory.
