About the TOML to Excel Converter
This TOML to XLSX converter turns config files from TOML into XLSX without installing software or uploading anything. It solves a common problem: fewer tools, libraries and APIs understand TOML. Converting to XLSX gives you an Excel workbook, ideal for working with data in Excel, Google Sheets and accounting or GST software.
The file is parsed with well-tested open-source parsers (the browser's JSON and XML parsers, js-yaml and smol-toml) and written back out as valid XLSX. Because everything happens on your own device, your config files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: nested objects are flattened into columns such as address.city, and the first list of records found in the file becomes the rows; invalid input is reported with the line of the problem so you can fix it.
How to use the TOML to Excel Converter
- Click "Choose files" or drag your TOML config files onto the box. You can add several at once.
- No settings are needed; indentation and types are handled automatically.
- Press "Convert to XLSX". The conversion runs on your device and shows its progress.
- Download each XLSX file, or use "Download all (ZIP)" when you converted several.
- Open the result in Microsoft Excel or Google Sheets to check it; your original TOML is never changed.
Tips & benchmarks
- Every sheet is kept and numbers stay numeric, so SUM and sorting work straight away in Excel.
- Lists of simple values are joined with semicolons, and lists of objects are kept as JSON text in one cell, so no information is lost.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the XLSX to a website or government portal.
Frequently asked questions
How do I convert TOML to XLSX?
Click "Choose files", select your TOML config files, adjust the options if you want, and press "Convert to XLSX". The XLSX downloads immediately; with several files you can download everything as one ZIP.
Is this TOML to XLSX converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your config files never leave your phone or computer and nothing is stored on News Appite's servers.
