Tool Overview

This tool formats Go code by running official gofmt in the browser with Go WASM for reviews, commit prep, and snippet cleanup.

Key Features

  • Uses official gofmt rules to produce standard Go formatting.
  • Includes sample loading, result copy, and dual-panel code editing.
  • All formatting runs in a browser-side WASM module without uploading code.

Formatting Engine

The Go code area uses official gofmt with Go WASM, running directly in the browser to produce output that better matches standard Go formatting.

The first run loads the WASM module, and later formatting continues locally in the browser. The engine follows official fixed gofmt rules and does not expose custom indentation widths.

Steps

  1. Paste Go code into the left panel.
  2. Click process to run official gofmt formatting.
  3. Review the result and copy it if needed.

Use Cases

  • Standardize Go code before commits.
  • Improve readability before code review.
  • Clean snippets for docs, blogs, and demo responses.

Notes

  • The tool never runs your app logic and only formats source text with gofmt.
  • If the source has syntax issues, review the output before applying it in a project.
