Convert DIF to PPM

The Data Interchange Format (DIF) file extension is a standardized format used primarily for importing and exporting spreadsheet data between different software applications. Originating in the 1980s, DIF was developed by Software Arts for their pioneering spreadsheet program, VisiCalc. Despite its age, DIF remains relevant due to its simplicity and ease of implementation, facilitating interoperability among various data processing tools. Its structured, plain text nature makes it particularly suitable for transferring tabular data while maintaining data integrity across different platforms.

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.
