What is an ETT file?
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.
How to open an ETT file
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.

What is an HTML file?
HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser, defined by the World Wide Web Consortium (W3C) and the WHATWG Living Standard. An HTML file consists of plain text tags that structure content into a Document Object Model (DOM), enabling the embedding of scripts (JavaScript), cascading style sheets (CSS), and multimedia. The format has evolved from SGML-based roots to the current HTML5 specification, which includes semantic elements and APIs for complex web applications.
How to open an HTML file
Operating systems universally support HTML rendering via pre-installed web browsers like Microsoft Edge (Windows), Safari (macOS), or Firefox (Linux). For source code modification, developers utilize specialized editors such as Visual Studio Code, IntelliJ IDEA, or Notepad++. No proprietary software is required, as the format is an open, non-proprietary standard text file.
