Convert XLSX to JSONLines

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 Lines, also known as JSONL, is a handy format for storing structured data that you can process one record at a time.

Each line in a JSON Lines file is a valid JSON object, typically representing a single record. The lines are separated by newline characters, making it easy to read and write sequentially.

This format works great for logging, streaming, and other scenarios where you want to process data line by line without parsing an entire JSON array.
