Frequently Asked Questions

What TOML structure works best?

Array-of-tables [[items]] converts best to CSV. Each array entry becomes a row with consistent columns.

What delimiter should I use?

Comma is standard. Use tab for TSV format. Use semicolon if your data contains commas.

How are nested values handled?

Nested keys are flattened: user.name becomes a column header. This preserves the full path to each value.

What if entries have different keys?

All unique keys become columns. Missing values in rows appear as empty cells in the CSV.

Can I convert simple TOML to CSV?

Simple key-value TOML converts to a single-row CSV. For meaningful CSV, use array-of-tables structure.

Will this open in Excel?

Yes, comma-delimited CSV opens directly in Excel. For European Excel, semicolon delimiter may work better.
