These pages load the Rust parser as WebAssembly. Paste or open text, inspect the resulting JSON, then take the same command to your shell.

JWT Decoder: Read a Token LocallyDecode a three-part JWT into its JSON header, payload, and signature bytes in your browser. Decoding does not verify the signature.
CRT Viewer and X.509 Certificate DecoderOpen PEM or binary DER X.509 certificates (.crt, .cer, .der) locally and inspect subject, issuer, validity, keys, extensions, and signatures as JSON.
CSR Decoder: Inspect a PEM Certificate RequestDecode a PEM certificate signing request into JSON and inspect its subject, public key, attributes, requested extensions, and signature data.
XML to JSON Converter and ViewerConvert XML to JSON locally in your browser, preserving attributes, text, repeated elements, comments, and empty elements in a predictable shape.
CSV to JSON Converter and ViewerConvert header-based CSV into an array of JSON objects locally. Quoted fields, UTF-8 BOMs, and comma, tab, or pipe delimiters are supported.
YAML to JSON Converter and ViewerConvert single- or multi-document YAML to structured JSON in your browser, with YAML scalar, sequence, and mapping types preserved where JSON allows.
URL Parser: Break a URL Into Its PartsParse an absolute URL into scheme, credentials, host, port, path, filename, query values, and fragment, with encoded and decoded component views.
TOML to JSON ConverterConvert a TOML document to JSON locally, preserving strings, numbers, booleans, arrays, nested tables, and explicit datetime representations.
TSV to JSON Converter and ViewerConvert a header-based tab-separated table into JSON objects locally, including quoted fields and records that span more than one line.
Plist to JSON Converter and ViewerRead XML or OpenStep property-list text as JSON locally, preserving nested values and making plist dates and byte data easier to inspect.
ASCII Table to JSON ConverterConvert a single-line ASCII, Unicode, Markdown, or fixed-width table into JSON records while preserving cell text and empty values.
Multiline ASCII Table to JSON ConverterConvert bordered ASCII or Unicode tables with wrapped cells and multiline headers into JSON, joining each logical cell with explicit newlines.
