Convert XLSX to JSON

XLSX files are Excel files that use the Office Open XML format, introduced with Microsoft Excel 2007.

XLSX files can contain multiple sheets, and each sheet can contain multiple rows and columns of data. They offer several advantages over the older XLS format.

Key features of XLSX files include:

• Improved compression, resulting in smaller file sizes
• Enhanced security features, including password protection and digital signatures
• Better recovery from file corruption
• Support for more rows (1,048,576) and columns (16,384) per sheet
• Compatibility with a wide range of applications and programming languages

XLSX files are based on XML and ZIP technologies, making them more accessible for third-party software to read and write.

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write and easy for machines to parse and generate.

JSON has become the de facto standard for data exchange on the web, and it is widely used in APIs.

Character encoding

As stated by the RFC 8259, we expect strings in uploaded JSON files to be encoded in UTF-8.

If your file contains non UTF-8 characters, you might get an error when parsing your data.
