About Remove Null Values
Remove Null Values drops fields whose value is null (or undefined) from each object in a JSON dataset, producing leaner data.
It is useful for shrinking API payloads, cleaning responses full of null fields, or preparing data for systems that reject nulls.
Only null fields are removed; empty "" values remain (use Remove Empty Rows/Fill Empty for those). Processed in the browser.
FAQ
Is my data sent to a server?
No. Remove Null Values runs entirely in your browser using client-side libraries. Your data never leaves your device.
