FAQ

What is YAML ⇄ JSON best for?

Convert between YAML and JSON formats bidirectionally with ease.

Does YAML ⇄ JSON upload or store my data?

This text tool is local-first in the browser and does not store your input for normal conversion workflows.

What's the difference between YAML and JSON?

YAML uses indentation and avoids brackets/quotes for simplicity, supports comments, and uses 'null' vs '~'. JSON is more explicit with brackets and quotes, widely used in APIs. Both are valid data interchange formats.

Why does my YAML conversion fail with 'bad indentation'?

YAML is whitespace-sensitive. Common issues: mixing tabs and spaces, inconsistent indentation depth, or unquoted strings containing colon-space (: ) which YAML interprets as key-value pairs.

Can I convert YAML with anchors and aliases?

The converter handles basic anchors (&anchor) and aliases (*alias). Complex merge keys (<<: *alias) may not fully resolve. Test with a simple example first.

Why are my quotes or special characters preserved differently?

JSON is stricter about quotes. YAML's output may add or remove quotes based on content type. For exact round-trip conversion, use the same tool consistently.

Which tools pair well with YAML ⇄ JSON?

Common next steps include JSON Formatter, JSON Validator. These related tools help continue the same workflow through generation, validation, formatting, or debugging.
