How do I convert an XLS file to TOML with LetsConvert?

Upload your XLS file using the converter page, select TOML as the target format, and click Convert. LetsConvert processes each sheet in the workbook: the sheet name becomes a TOML table, and each row in the sheet becomes an array of tables (or dictionaries). Download the resulting .toml file and use it in your project.

Why should I convert XLS to TOML instead of keeping it as a spreadsheet?

TOML is a lightweight, human-readable config format used by tools like Cargo, pip, and many custom applications. Converting XLS to TOML turns your spreadsheet data into a configuration file that can be version-controlled, reviewed in code reviews, and deployed directly to servers. TOML files are also significantly smaller than XLS since they store only data without binary formatting, making them ideal for software configuration.

What happens to formulas, multiple sheets, and formatting during the conversion?

During the conversion, formulas are evaluated to their current values, and all visual formatting (fonts, colors, cell borders) is removed. Each worksheet becomes a separate TOML table, and if your sheet uses a header row, those headers are used as keys; otherwise, default keys like column1, column2 are generated. Data types such as strings, floats, and booleans are preserved in the TOML output, while empty cells are omitted to keep the file valid and clean.

Is XLS-TO-TOML free to use?

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

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Is there any software installation required?
