Extract text from EPP files
To convert your EPP file to another format, you need Subiekt GT or other Data software.
To convert other file formats to the "ERP Exchange File" file type, you need software like Subiekt GT or a similar tool.
The .epp extension represents a collision of proprietary formats, most notably the EDI++ business data exchange files used by InsERT software (e.g., Subiekt GT, Rewizor GT). These text-based files contain invoices, inventory, and contractor data designed for seamless synchronization between Polish accounting systems. While efficient for B2B data transfer, they are unreadable to standard users without the source software, creating a "black box" effect for accountants needing to verify raw data. Users frequently need to convert these into human-readable Excel (.XLSX) spreadsheets or PDF reports to audit financial records without purchasing an InsERT license.
Simultaneously, .epp files serve as project containers for creative software, including the legacy Serif PhotoPlus (now discontinued) and Easy Poster Printer. In this context, the file holds raster layers, text layouts, and print settings. These are often "zombie files" - users possess the data but lack the obsolete software to open it. For these users, the urgent goal is converting proprietary projects into standard JPG, PNG, or TIFF images to preserve visual memories or print designs before the original tools become completely inaccessible on modern OS environments.
Convert.Guru analyzes your EPP file, detects the exact format, and lets you read the text inside.
Users also converted PDF, EEP, EDI, EPUB, EPS, ZIP, PNG, JPG, CR2, CR3 and CRW files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our EPP converter.
