YAML Pretty Print
More about the YAML Pretty Print
YAML generated programmatically or written quickly under time pressure is often technically valid, no syntax errors, nothing actually broken, but inconsistently indented in a way that makes it genuinely hard to read and review, two spaces in one block and four in another, which is a formatting problem rather than the kind of error that stops a file from parsing at all. This tool formats and indents YAML with syntax highlighting and configurable spacing, cleaning up already-valid YAML for readability rather than hunting for a syntax error that's actually breaking it. Useful for reformatting a programmatically generated YAML file into consistent, readable indentation, cleaning up a config file that mixes indentation styles before a code review, or applying syntax highlighting and consistent spacing to a YAML file that's already valid but genuinely hard to read as written.
Format and indent YAML with syntax highlighting and configurable spacing. The YAML Pretty Print is one of 900+ free developer tools on Toolblip - all open to use without a signup.
