Remove Nulls from JSON

The Remove Nulls tool walks your entire JSON document and deletes every property whose value is null, at any depth. This produces leaner payloads and cleaner configs where absent data is simply omitted rather than explicitly set to null. You control whether nulls inside arrays are dropped or preserved to keep positions intact.

• Recursively removes null-valued properties from every nested object
• Optionally drops null elements inside arrays or keeps them to preserve indices
• Leaves all non-null values, including false, 0, and empty strings, untouched
• Optionally prunes objects that become empty after nulls are removed
• Reports how many null values were removed
• Copy the cleaned document in one click

4. 4

   Copy the result

   Use the leaner JSON in your API request, config, or storage.

• Trimming null fields from an API payload before sending it
• Cleaning database exports where missing values serialize as null
• Reducing config noise by omitting explicitly-null settings
• Preparing JSON for merge operations where null should mean absent
• Shrinking documents before hashing or comparison
