Convert XLSX to JSON

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

Like XLS files, XLSX files can have 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:

• Better 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
• Works with a wide range of applications and programming languages

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

JSON (JavaScript Object Notation) is a lightweight data format that uses human-readable text to store and transmit data objects. It's widely used for data exchange between web applications and servers, API responses, configuration files, and data storage.

Technical Details

JSON represents data with key-value pairs in a nested structure. It supports strings, numbers, booleans, arrays, objects, and null values, making it flexible for various data types. JSON is language-independent but derived from JavaScript syntax, making it particularly popular in web development. JSON files use the .json extension and have a MIME type of application/json.

Advantages

• Supports complex, nested data structures
• Native support in JavaScript and most modern programming languages
• Self-describing and human-readable
• Compact compared to XML and other structured formats
• Language-independent and widely adopted as a standard
• Perfect for API responses and data transfer
• No special parsing tools needed - standard in most programming languages

Limitations

• Not ideal for tabular data analysis
• No support for comments or metadata
• Can be verbose for large datasets
• No schema validation built into the format itself
• Nested structures can be difficult to analyze in spreadsheet tools
• Converting to tabular formats requires flattening of nested objects
