XLS to JSON

Q: Why convert XLS to JSON?

An .xls workbook is the binary workbook format of Excel 97–2003, limited to 65,536 rows; a JSON file is the data format of web APIs and apps — lists of records with named fields. Legacy systems export .xls, while the code that needs the data wants JSON.

Turn old .xls rows into JSON records. Check and change it in Mega Excel Studio, then download.

Convert XLS to JSON — the right way

Legacy systems export .xls, while the code that needs the data wants JSON. Drop your .xls workbook above; it opens in Mega Excel Studio with the export window set to JSON, so you can look it over, change anything and download. Each row becomes a record named by the header row, numbers kept as numbers. A JSON file is the data format of web APIs and apps — lists of records with named fields, and opens in every programming language, API tool and database.
