Messy API payloads slow everyone down. A solid JSON formatter helps you beautify, validate, and minify JSON in one place.
What you can do
- Pretty print JSON for readable debugging
- Validate JSON and catch missing commas or braces
- Minify JSON for compact payloads
- Browse nested objects in a tree view
Open the free JSON Formatter and paste your payload.
Common JSON mistakes
- Trailing commas
- Single quotes instead of double quotes
- Unescaped characters in strings
- Comments (not valid in strict JSON)
Developer tip
Keep a formatter tab pinned while integrating webhooks or inspecting network responses. Pair it with our password generator and QR tools for everyday shipping work.
