Convert ET to XLS (Excel)

The ET file extension is associated with Kingsoft Spreadsheets, part of the WPS Office suite. It is used to store and organize financial data, such as balance sheets, expense statements, and invoices, in a format of rows and columns. The ET file supports formulas and charts, and it can be converted to more common formats like XLS or XLSX. The WPS Office suite, similar to Microsoft Office, offers tools for word processing, spreadsheets, and presentations.

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.
