Convert ET to XLSX (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 XLSX file extension, standing for "Excel Spreadsheet", represents a widely used format for Microsoft Excel spreadsheets. Introduced in Excel 2007, XLSX replaced the older XLS format, utilizing the Office Open XML (OOXML) standard to store data more efficiently and reduce file size. It supports advanced features such as pivot tables, charts, formulas, and macros, essential for data analysis and reporting in various professional settings. The transition to XLSX provided enhanced security, improved data recovery, and greater compatibility with other software applications, solidifying its status as a pivotal tool in data management and business intelligence.
