Free online functions: steps and checks

Beautify JavaScript Online for Free

Paste JavaScript source and apply formatting to make the code easier to read. Review blocks and statements in the beautified result before copying it into your editor for further inspection or changes.

Format JavaScript Indentation for Free

Bring unevenly spaced JavaScript into the formatter to inspect a more readable arrangement. Compare the result with the source where needed; tidy indentation alone does not establish that a script is valid or correct.

Try Basic JavaScript Text Compression for Free

Use the reverse action to inspect a compact version of pasted source while retaining the original. Compression is text-based and can change strings or comments, so use a tested build minifier for production code.
