Convert ETT to XLS (Excel)

The ETT file extension stands for Kingsoft Spreadsheets Template. It is used in the WPS Office suite by Kingsoft to store spreadsheet templates, which serve as starting points for creating new spreadsheets. These templates are commonly used for financial budgets and data organization. The ETT format allows for the duplication of spreadsheets with similar layouts and information, and can be converted to other spreadsheet formats like XLSX.

The XLS file extension, short for "Excel Spreadsheet", is a legacy format used by Microsoft Excel for storing spreadsheet data. Introduced with Excel 2.0 in 1987, it was the primary format until the introduction of XLSX in 2007. XLS files contain data organized in rows and columns, supporting formulas, macros, and various formatting options, making them essential for data analysis and financial reporting. Despite being replaced by the more robust and secure XLSX format, XLS files remain widely used in many legacy systems and applications.
