Common Mistakes to Avoid

⚠️

TOML datetime handling

Solution: TOML has native datetime types that become strings in JSON. Check if date format matches your needs.

⚠️

Inline table syntax

Solution: TOML inline tables {a=1,b=2} may parse differently than regular tables. Verify complex structures.

⚠️

Array of tables

Solution: [[items]] syntax creates arrays of objects. Ensure your converter handles this TOML feature correctly.
