ETT to CSV 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.

A Comma-Separated Values (CSV) file is a delimited text file format codified under RFC 4180 that uses commas to separate values and newlines to separate records. The format stores tabular data (numbers and text) in plain ASCII or Unicode text, where each line constitutes a data record with identical field sequences. It lacks a formalized schema for styling or formulas, relying solely on character separation for data structure, making it a standard for platform-independent data exchange between disparate database management systems (DBMS).

Due to its plain text architecture, CSV files possess universal native support across all major operating systems. They can be viewed and edited using simple text editors like Microsoft Notepad or Vim, but are optimally managed with spreadsheet software such as Microsoft Excel, LibreOffice Calc, or Google Sheets, which parse the delimiters to render the data into columns.
