Convert XLTX to PPM

The XLTX file extension stands for "Excel Open XML Spreadsheet Template" and is a file format used by Microsoft Excel. Introduced with Excel 2007 as part of the Office Open XML standard, it enhances the functionality of the older XLT format. XLTX files serve as templates that store predefined formatting, formulas, and styles, enabling users to create consistent and structured spreadsheets efficiently. This format supports advanced features and reduces file size, ensuring compatibility across different platforms. It remains a crucial tool for IT specialists to streamline repetitive tasks and maintain uniformity in data presentation.

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
