About JSON Toolbox
An all-in-one developer toolbox for parsing JSON payloads. Paste minified, unformatted, or raw API JSON strings to beautify them with adjustable indentations, run syntax validations to capture formatting bugs, compress large JSON strings by removing spaces/breaks, or automatically map key-values to produce perfectly compiled TypeScript interface declarations.
