Kingsoft Spreadsheets Template (.ett)
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.
