Code & Dev Tools

Paste a 400-line API response into JSON Formatter & Beautifier and it names the line and column of the first syntax error instead of just refusing to parse. That is the standard the rest of this group is held to. JWT Decoder splits a token into its three segments and reads exp against your own clock. JSON Diff Checker reports which keys changed between two payloads rather than showing you two walls of text. Unix Timestamp Converter settles the seconds-versus-milliseconds argument that costs everyone an afternoon at least once. None of it is uploaded, which matters more in this category than anywhere else on the site: tokens and request bodies are exactly what you least want sitting in a stranger's log file.
