JSON Clean Tools

JSON Cleaner

Clean noisy but valid JSON: trim string values, remove null or empty values you choose, sort object keys, deduplicate array items, and optionally strip JSONC-style comments, with a before/after preview.

{"name":" Alice ","x":null}

{"name":"Alice"}

null removed, keys sorted

JSONL Cleaner

Clean JSON Lines files: remove invalid or blank records, trim string values, deduplicate by full line or a selected key, and export a valid JSONL file with a discard report.

{"id":1,"name":" Alice "}

bad line

{"id":1,"name":"Alice"}

invalid record discarded
