How do I format code on this page?
Paste code into the left editor or load a file, choose the options you need, and select Format. Review the result on the right, then copy or save it.
Protobuf Formatter is a tool that helps to make Protocol Buffer files more readable by automatically formatting them. It can parse and pretty-print the protobuf files in a standard format with indentation, line breaks, and proper syntax highlighting. This makes it easier for developers to navigate the files, understand their structure, and make modifications. The tool is useful for large protobuf files or those with complex nested structures.
Paste code into the left editor or load a file, choose the options you need, and select Format. Review the result on the right, then copy or save it.
The input must match the selected language or syntax. Check incomplete statements, unmatched brackets or quotes, and a dialect or mode that does not match the input, then format again.
A code formatter reads language-aware tokens and nested structures, then rewrites indentation, spacing, and line breaks according to a consistent rule set. It does not compile or run the program, so formatting is not a correctness or security check.
The official Protocol Buffers style uses 2 spaces and an 80-column limit, so the page defaults are the recommended starting point. Choose a formatting style, indent width, and column limit for messages, fields, services, enums, and comments in .proto files.
