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.
TypeScript Formatter beautifies TypeScript and TSX with consistent indentation, spacing, line wrapping, semicolons, quotes, and trailing commas. It understands interfaces, type aliases, generics, enums, decorators, modern JavaScript syntax, and React components.
Choose the standard TypeScript parser or Babel TypeScript parser, select tabs or a fixed number of spaces, and set a predictable print width. Syntax errors are reported separately instead of being mixed into the formatted output.
Formatting runs in your browser, so source code is not uploaded to a server. Press Ctrl+Enter or Command+Enter to format, then copy or save the result.
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.
Start with the TypeScript parser, 2 spaces, and 80 or 100 columns. Keep semicolons, quotes, and trailing commas consistent with the repository. Choose the TypeScript or Babel TypeScript parser, indentation, line width, trailing commas, semicolons, and quote style for TypeScript or TSX.
