Beautify, minify, or validate JSON instantly. Errors surface with line and column.
Three actions for working with JSON in your browser. Beautify pretty-prints with your chosen indent (2 or 4 spaces) so you can actually read it. Minify strips all whitespace for the smallest possible payload — handy for fitting JSON into URL query strings or static asset bundles. Validate only parses the input and tells you if it's valid, with line and column for any error. Runs entirely client-side; your data is never uploaded.
