Convert EXF to another file type
To convert EXF project files to another format, you need RIB CostX or other Data software.
Convert a file to EXF
To convert other file formats to the "Project Data File" file type, you need software like RIB CostX or a similar tool.
About EXF files
The .exf extension primarily belongs to CostX Project Data files created by RIB CostX (formerly Exactal). These files store building estimation, 2D/3D BIM takeoff data, and costing spreadsheets. Another common use is for Mirillis Action! recorded user input or compressed video data, as well as EXMARaLDA XML Exchange Formats and Daimler vehicle programming exchange files. You can open CostX files with RIB CostX. Mirillis files require Mirillis Action!. EXMARaLDA uses its own specialized linguistics suite. These are highly proprietary data containers. You cannot open a CostX .exf file in a standard spreadsheet tool like Microsoft Excel without first exporting it from the native software. Mirillis .exf files are equally restricted and cannot be played in standard media players. Sharing these files with clients or colleagues who lack an expensive software license is a major bottleneck. For CostX, the ideal conversion targets are .XLSX or .CSV for data sharing, or .PDF for static reporting. Mirillis files should be exported to standard .MP4 or .AVI video formats. Note that converting CostX to standard spreadsheets will strip out interactive 3D BIM data and linked takeoff measurements. This file format is heavily closed and proprietary. Standard online converters fail to process it because the internal structure requires the original rendering engine to decode. Often only the original software can properly read or export the data. However, just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your EXF file, detects the exact format, and lets you read the text inside.
If you want to convert EXF file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use RIB CostX or similar software from the "Construction Estimating Project Data" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to EXF, try RIB CostX or another comparable tool in the "Construction Estimating Project Data" category.
The EXF 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 EXF converter.
