ET to BMP Converter

The ET file extension denotes a spreadsheet created by WPS Office (formerly Kingsoft Office), specifically within the WPS Spreadsheets application. It serves as the proprietary binary or XML-based container for the suite, functionally analogous to Microsoft's XLS format. The file encapsulates cell data, complex formulas, chart objects, and layout formatting. While historically proprietary, modern iterations often adhere to structures compatible with Microsoft Object Linking and Embedding (OLE) specifications to ensure interoperability.

ET files are natively supported by the WPS Office suite, available on Windows, Linux, macOS, and Android. While Microsoft Excel does not natively render ET files without conversion, users can convert them to XLS/XLSX using WPS or utilize generic file viewers. LibreOffice Calc provides partial support for importing Kingsoft formats via specific import filters.

The BMP (Bitmap) format, formally known as the Device Independent Bitmap (DIB) file format, is a raster graphics standard developed by Microsoft for the Windows operating system. The file structure consists of a file header (BITMAPFILEHEADER), an information header (typically BITMAPINFOHEADER), a color table, and the pixel array. Data is stored as a grid of pixels with color depths ranging from 1-bit to 32-bit, typically uncompressed, though the format supports lossless Run-Length Encoding (RLE4 or RLE8) and Huffman 1D compression for specific bit depths.

Due to its simplicity and documentation as a core Windows standard, BMP files possess near-universal compatibility. They can be opened natively by virtually all image viewers and web browsers across Windows, macOS, and Linux without additional software. Standard utilities include Microsoft Paint, Apple Preview, and Windows Photos. For advanced manipulation, pixel-based editors like Adobe Photoshop and CorelDRAW are recommended, though the format is rarely used for complex editing due to its large file size.
