Online C/C++ Formatter

Online C/C++ Formatter

The online C/C++ formatter is used to organize C and C++ code indentation and whitespace. It supports indentation and beautification of structures such as functions, structs, preprocessor directives, and pointers, as well as whitespace compression and bracket and quote balancing checks.

C/C++ Formatting

Code indentation is automatically organized based on bracket structure, keeping function, struct, conditional, and loop levels clear. It supports 2-space, 4-space, 8-space, and Tab indentation, while preprocessor directives such as #include remain at the beginning of the line.

C/C++ Compression

Comments and unnecessary whitespace are removed while string literals are preserved exactly as written, producing more compact code.

Basic Validation and Error Location

The tool detects basic structural issues such as mismatched brackets, unclosed quotes, and unterminated comments and indicates the affected line. Clicking the location can directly select the problematic position in the input box. This tool performs structural-level checks rather than compiler-level syntax validation.

Use Cases

• Clean up C/C++ code snippets with inconsistent indentation.
• Standardize basic C/C++ indentation styles across a team.
• Check basic balancing issues involving brackets and quotes.
