  1. Paste your YAML data.

  3. Run the tool or keep live processing enabled.
  4. Review quality score, warnings, and structure summary.
  5. Copy or download the output.

What this tool does

YAML Formatter helps prepare YAML data for review, spreadsheet work, configuration cleanup, database import, or safer data exchange.

Input → parse rows or structure → clean/format/validate/convert → quality score → export-ready result

The tool focuses on practical browser-side diagnostics. It does not upload pasted data to a server.

Example

Example: paste messy YAML data, run the tool, then check row/column or key/depth statistics before copying the output.

Use cases

  • Prepare data before database import.
  • Clean spreadsheet exports.
  • Validate configuration files.
  • Convert delimiter formats for Excel, Google Sheets, or APIs.

Tips for better output

  • Keep headers unique.
  • Check inconsistent rows before import.
  • Use spaces for YAML indentation.
  • Review duplicate and empty-value warnings.

Processing details

The processor detects delimiters or indentation, parses the content, applies the selected operation, and generates statistics, warnings, and a score.

CSV parsing supports common quoted-cell rules. YAML checks are practical structural diagnostics, not a full schema validator.

FAQ

How do I format YAML without breaking indentation?

Paste the YAML, choose 2 or 4 spaces, then run YAML Formatter. The tool normalizes indentation and reports suspicious lines before you reuse the file.

Why is my Docker Compose YAML invalid?

Common causes include tabs, inconsistent list indentation, missing colons, duplicate service keys, or values placed at the wrong nesting level.

Can I validate GitHub Actions YAML online?

Yes. Paste the workflow YAML and check indentation warnings, duplicate keys, empty values, and common YAML structure issues.

How do I check Kubernetes YAML formatting?

Use the structure report to inspect apiVersion, kind, metadata, list blocks, nesting depth, and indentation consistency.

Why does YAML fail when tabs are used?

YAML normally expects spaces for indentation, so tabs can make parsers reject an otherwise readable configuration file.
