Convert HOP to another file type
To convert HOP CNC programs to another format, you need HOPS CAD/CAM or other Cad software.
Convert a file to HOP
To convert other file formats to the "CNC Toolpath File" file type, you need software like HOPS CAD/CAM or a similar tool.
About HOP files
A .hop file is primarily a Woodworking CNC (Computer Numerical Control) program file created by HOPS CAD/CAM software, used to control HOLZ-HER and other industrial routing machines. In other contexts, it can be a game asset archive for Heavy Iron Studios, a project database for Hopper Disassembler, or a HoloPlay holographic media file from Looking Glass Factory.
These formats share a common disadvantage: they are highly proprietary. CNC .hop files require expensive, specialized industrial software to open, modify, or even view. They are not supported by standard CAD tools or web browsers. Game asset archives and database files are completely useless outside of their specific engines, locking away the data inside.
When working with CNC .hop files, the best conversion targets are standard vector formats like DXF or DWG. This allows the geometry to be viewed in AutoCAD or standard vector editors, though machine-specific instructions like spindle speeds and toolpaths will be permanently lost. HoloPlay files, conversely, are simply renamed ZIP files and can be extracted to access the underlying MP4 or PNG media.
Because CNC and game .hop files are closed, proprietary formats, standard online converters fail to process them. Often, only the original software can properly read or export the data. Our system will inspect the file, show text or internal content, and if our analysis detects a supported underlying or embedded format (like a ZIP structure), viewing or extraction may still be possible.
Convert.Guru analyzes your HOP file, detects the exact format, and lets you read the text inside.
If you want to convert HOP file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use HOPS CAD/CAM or similar software from the "Woodworking CNC Machine Control" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to HOP, try HOPS CAD/CAM or another comparable tool in the "Woodworking CNC Machine Control" category.
The HOP Converter Story
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 HOP converter.
