How do I convert an XLSX file to TOML on LetsConvert?

Upload your XLSX file, select TOML as the output format, and click Convert. Each worksheet becomes a TOML table, and every worksheet row is converted to a TOML subtable with cell values mapped to TOML types (strings, integers, floats, booleans, dates).

Why should I convert XLSX to TOML instead of using Excel directly?

TOML is a human-readable configuration format with strict type support, making it perfect for application settings, build scripts, and CI/CD pipelines. Converting XLSX to TOML lets you manage data in familiar spreadsheet tools, then export validated, structured configs that are easy to version-control and parse.

What happens to formulas, dates, and formatting during XLSX to TOML conversion?

Formulas are evaluated and their current results are exported as static values. Dates become ISO 8601 strings, and numeric cells preserve their stored precision. Visual styling like fonts, colors, and merging is not carried over, as TOML is a plain-text format focused on data structure, not presentation.

Is XLSX-TO-TOML free to use?

Yes, XLSX-TO-TOML on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?
