Tips for YAML to JSON Conversion
Indentation Matters
YAML uses indentation for structure. Make sure your indentation is consistent (all spaces, no tabs) for correct parsing.
Use the Sample First
Load the sample data to understand how different YAML structures convert to JSON before pasting your own data.
Watch for Special Values
YAML treats 'yes', 'no', 'on', 'off' as booleans. If you want them as strings, wrap them in quotes in your YAML.
