JSON to XLS Converter

Convert JSON files to XLS. Free and without uploading.

This tool converts JSON files to XLS. JSON is the text format programs use to exchange data.

XLS is the old binary format of Excel 97–2003; older software and some institutions still require it. All sheets, numbers and dates are carried over. Some formatting, such as cell colours, may be lost in the target format.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your JSON files, paste them, fetch one from a link, or use "Choose files".
2. The target format is preselected; you can add several files at once.
3. Press "Convert" and download the XLS files.

Is anything lost when converting JSON to XLS?

The content is kept; formatting the target format doesn’t support (such as colours or fonts) may be lost.

How many files can I convert at once?

There is no limit. Download the results one by one or as a ZIP.

Are my files uploaded?

No. Your JSON files are converted to XLS inside your browser.
