WebSocket Message Formatter
Beautify and validate JSON messages intended for WebSocket payloads.
Beautify and validate JSON messages intended for WebSocket payloads.
A WebSocket message formatter makes JSON or text payloads easier to read while debugging real-time applications. It can help reveal fields, nesting, and formatting problems in message data.
Paste a message payload, choose the relevant formatting action, then copy or compare the formatted output.
Formatting improves readability but does not validate every protocol rule. Confirm the expected message schema and frame type.
Formatters reorganize text or structured data to improve readability. Start with a small valid example, compare the result with the source, and verify that the target parser still accepts it. Pay attention to these page fields: Raw WebSocket Payload, Formatted Output. Confirm which fields are inputs, options, or output areas before processing.
Treat calculated or parsed performance values as diagnostic evidence. Compare like-for-like measurements and validate suspected issues with browser or field data.
