Delete properties from JSON by name — a comma-separated list, removed at every depth. Ideal for stripping tokens, hashes and internal fields before sharing a payload.
Show calculation steps
Processed privately in your browser — nothing you paste is uploaded, logged or stored.
Redaction and slimming in one pass
The most common reason to remove properties is safety: before a payload goes into a bug report, a support ticket or documentation, the tokens, hashes and emails need to come out. List the keys, comma-separated, and they are removed wherever they occur — including inside arrays — with a count so you can verify. Because everything runs in your browser, the sensitive payload never leaves your machine in the first place.
Worked example
Removing password_hash, session_token:
{
"id": 1,
"name": "Asha",
"password_hash": "x9f2…",
"profile": { "bio": "Editor", "session_token": "def456" }
}Output — 2 properties removed:
{
"id": 1,
"name": "Asha",
"profile": { "bio": "Editor" }
}When to use it
- Redacting secrets and personal data before sharing a payload.
- Dropping bulky fields (base64 blobs, debug info) to slim a document — the Size Calculator tells you which ones are worth it.
- Removing noisy timestamps before diffing two responses.
Limitations to know
- Removal is by key name everywhere — there is no path scoping in this version.
- A secret stored under an unexpected key name survives; skim the output before you share it.
Common errors and fixes
- “None of the requested keys were found” — check spelling and case, or switch off case-sensitive matching.
- Empty shells left behind — an object whose only key was removed becomes {}; chain the Empty Value Remover to clean those up.
How to use the JSON Property Remover
- Paste your JSON.
- List the keys to remove, separated by commas (for example: password_hash, session_token).
- Click "Remove properties".
- Verify the count in the stats line and copy the cleaned JSON.
Frequently asked questions
Why remove properties from JSON?
The classic case is sharing a payload safely: strip tokens, password hashes, emails and internal IDs before pasting a response into a bug report, a support ticket or documentation. It also slims payloads and removes noisy fields before diffing.
Are properties removed at every depth?
Yes — a listed key is removed wherever it occurs, including inside arrays of objects. The stats line counts every removal so you can sanity-check the result.
Since this runs in my browser, is it safe for sensitive data?
The processing never leaves your machine — nothing is uploaded, logged or stored, which is exactly why a browser-side remover is the right tool for redacting secrets. Still, review the output before sharing; a secret under an unexpected key name survives.
What happens to the structure after removal?
Objects keep their other keys in order; nothing collapses or reindexes. If removals leave empty objects behind and you want those gone too, run the result through the Empty Value Remover.
