Messy JSON is a debugging bottleneck. The JSON Prettifier & Minifier formats raw API responses into readable indented output or compresses them into compact payloads — on the spot, with no server upload.
Working with encoded data? Use the Base64 Encoder or URL Encoder for transport-safe encoding.
Prettify adds indentation and line breaks for readability. Minify removes all whitespace to reduce payload size for production use.
No. Prettifying only changes formatting — the data structure and values remain identical.
Common issues: trailing commas, single quotes instead of double quotes, unquoted keys, or comments — none of which are valid JSON.
