Convert POST to another file type
To convert your POST file to another format, you need GibbsCAM or other Cad software.
Convert a file to POST
To convert other file formats to the "CAM Configuration File" file type, you need software like GibbsCAM or a similar tool.
About POST files
A .POST file is a critical configuration script used in Computer-Aided Manufacturing (CAM), primarily by software like GibbsCAM and Mastercam. It functions as a translation dictionary - or "driver" - that converts the generic, internal toolpaths created by a programmer into the specific dialect of G-code required by a particular CNC machine controller (e.g., Fanuc, Haas, Siemens).
A major limitation for users is that .POST files are not universal; a file configured for a 3-axis mill will not work on a 5-axis lathe, effectively locking manufacturing data to specific hardware. Additionally, while many .POST files are technically text-based, they often contain proprietary syntax or compiled binary sections that appear as gibberish in standard text editors. Users frequently mistakenly try to "convert" these files to 3D models (like STL or STEP), but they contain instruction logic, not geometry.
For review or editing, the best practical conversion is to TXT, which allows you to inspect the post-processor logic in a safe text environment. To generate the actual machine instructions, you do not convert the file directly; instead, you must process your project using the .POST file within the CAM software to output NC, NCC, or TAP files.
Convert.Guru analyzes your POST file, detects the exact format, and lets you read the text inside.
If you want to convert POST file to STORY, GET, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use GibbsCAM or similar software from the "CNC Machine Post-Processor" 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 POST, try GibbsCAM or another comparable tool in the "CNC Machine Post-Processor" category.
The POST 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 POST converter.
