Convert XLS to SQLite

XLS files are Excel files that use the Binary Interchange File Format (BIFF). This was the default format for Excel versions 97-2003.

XLS files can have multiple sheets, and each sheet can contain multiple rows and columns of data. They support various data types, including text, numbers, dates, and formulas.

Key features of XLS files include:

• Works with older versions of Excel and other spreadsheet software
• Can store formatting information, charts, and macros
• Smaller file size compared to newer formats like XLSX
• Limited to 65,536 rows and 256 columns per sheet

While XLS files are still widely used, they're gradually being replaced by the more modern XLSX format.

SQLite is a C-language library that implements a small, fast, self-contained, highly reliable, full-featured, SQL database engine.

It's the most used database engine in the world, embedded in many applications. SQLite is serverless and needs no configuration, making it ideal for local/client storage in application software.
