JSON and Data Tools

Parse CSV text (quotes, escaped quotes, embedded commas and newlines) into JSON rows, detecting the delimiter.

Encode or decode text as base64, base64url, hex, URL percent-encoding or HTML entities; invalid input is reported, not guessed.

MD5, SHA-1, SHA-256 and SHA-512 digests of UTF-8 text, in hex and base64, for checksums and integrity checks.

Structural diff of two JSON documents: every added, removed, changed or retyped path.

Pretty-print or minify JSON, optionally sorting keys, and report the size before and after.

Extract one value from JSON by a simple path such as a.b[0].c, with its type; reports exactly where a path breaks.

Check whether text is valid JSON; if not, return the error with line and column. If valid, report type, size and depth.

Split a URL into scheme, host, port, path, query parameters and fragment, and flag credentials, IP hosts and odd ports.

Validate a UUID and read its version, variant and, for v1 and v7, the embedded timestamp.
