JSON pick or omit keys

Client

Choose keys to keep (pick) or drop (omit) at the top level only. Root value must be an object or an array of objects.

Pick or omit keys

?

Only top-level keys on each object are changed. Key matching is case-sensitive. Root must be an object or an array of objects.

Mode

Common use cases

  • Trim API response objects to id/name fields before saving a sample.
  • Strip noisy or sensitive top-level keys from an array of row objects.

Common mistakes to avoid

  • Expecting nested keys to be removed

    Only the root object’s top-level keys (or each array element’s top-level keys) are affected. Nested properties stay as-is.
