ETT to OTS Converter

An ETT file is a spreadsheet template format utilized by the WPS Office Spreadsheets application. Similar to Microsoft's XLT or XLTX formats, it contains pre-defined layout structures, formatting styles, formulas, and macros intended to serve as a blueprint for generating multiple .et spreadsheet files with consistent styling. The format allows users to standardize corporate reporting or invoice structures without altering the original master data.

Native interaction with ETT files requires the WPS Office suite. Opening the file typically instantiates a new, unsaved .et spreadsheet based on the template's parameters rather than editing the template itself. Users wishing to edit the template structure directly must explicitly choose the 'Open' command within WPS Spreadsheets rather than double-clicking the file.

The OpenDocument Spreadsheet Template (OTS) is a file format defined by the OASIS OpenDocument standard (ISO/IEC 26300) specifically for creating reusable spreadsheet blueprints. Structurally identical to the ODS format, it uses ZIP compression to package XML content and styles. The primary technical distinction lies in the file header flags, which instruct the software to open a new, untitled instance of the spreadsheet rather than modifying the original template file, preserving the source data structure and formulas.

OTS files function seamlessly with ODF-compliant software including LibreOffice Calc and Apache OpenOffice across all major operating systems. While Microsoft Excel can open these files, users may need to manually select the file type in the open dialog. Double-clicking an OTS file typically launches a new workbook based on the template rather than opening the template file itself for editing.
