Online JSON formatter and validator
Paste compact or inconsistently indented JSON to apply consistent formatting and find syntax issues such as missing quotes, commas, or brackets. Formatting changes whitespace only and preserves the data structure of valid JSON.
Does formatting JSON change its data?
Formatting rearranges whitespace and line breaks only; it does not change parsed keys, values, or array order. If the syntax is invalid, the tool reports the parse error and keeps your original input.
