Extract text from CNC programs and scripts (FNC)
To convert FNC scripts to another format, you need Fanuc CNC or other Developer software.
To convert other file formats to the "CNC Program & Script" file type, you need software like Fanuc CNC or a similar tool.
The .fnc file extension serves multiple specialized roles, most commonly as a CNC Machine Program or an Oracle PL/SQL Function Script. In manufacturing, it stores G-code instructions used by Fanuc or Fagor Automation machines to dictate exact milling, cutting, and structural steel fabrication paths. In enterprise IT environments, Oracle Database utilizes it to store custom server-side functions. Regionally, it also appears as proprietary fiscal drive data from ATOL trade registers.
Opening these files locally is notoriously frustrating. While Oracle scripts and CNC instructions are fundamentally plain text, the obscure .fnc extension causes web browsers and basic text editors to reject or misinterpret them. Furthermore, dedicated CAM software for CNC simulation is heavily proprietary, hardware-locked, and extremely expensive. Fiscal .fnc files are completely encrypted and useless outside their native accounting ecosystems.
To break out of these vendor locks, you must convert the file. For immediate code review, web sharing, or archiving, convert your developer scripts to TXT, SQL, or PDF. For manufacturing compatibility, convert CNC toolpaths to standard NC or GCODE formats so generic simulators can read them. Drop your file here to view and convert it securely right in your browser.
Convert.Guru analyzes your FNC file, detects the exact format, and lets you read the text inside.
Users also converted ENC, XLSX, RTF, JPG, PDF, TXT, PRV, CLR and ATM files.
If you want to convert FNC file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Fanuc CNC or similar software from the "CNC Programming & Database Scripts" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to FNC, try Fanuc CNC or another comparable tool in the "CNC Programming & Database Scripts" category.
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 FNC converter.
