Frequently Asked Questions

What is the difference between delimiter options?

Comma is the default and most common in TOON format. Tab delimiter often tokenizes better for LLMs and reduces quote-escaping needs. Pipe delimiter is useful when your data contains many commas, similar to CSV standards. The formatter lets you easily switch between them for optimal token efficiency.

What does the length marker option do?

The length marker adds an optional # prefix to emphasize that the bracketed value is a count, not an index. For example, [3] becomes [#3]. Both are valid TOON formats.

Can I convert between different TOON delimiter types?

Yes! That's one of the main features. Input TOON with comma delimiters and convert to tab or pipe delimiters instantly. The formatter validates and reformats your data automatically.

Does formatting change my data?

No! The formatter only changes the presentation (delimiter, spacing, markers) but preserves all your data values and structure. It's completely safe to reformat TOON data.

What indentation should I use?

2 spaces is the TOON standard and most common. Use 4 spaces if that matches your team's coding standards or if you prefer more visible indentation. Both are valid.

Is the TOON formatter free?

Yes, completely free with no limitations. Format unlimited TOON files with all options available. Also check out our JSON to TOON, TOON to JSON, and TOON Validator tools.
