Convert Weather data files (GRB) online for free
The converter easily converts your GRB Data files to various formats - free and online. No wgrib2 or or other Data software needed.
The converter also works in reverse, so you can convert other "Weather Data & CAD" formats to GRB without using software like wgrib2 or a similar tool.
The .GRB file extension is highly overloaded, meaning it is used by completely different industries for fundamentally different purposes. Most commonly, it represents a Gridded Binary (GRIB) file, a standardized format defined by the World Meteorological Organization to store historical weather data and forecast models. Because GRIB files are heavily compressed binary data, they are completely unreadable in standard text editors and require specialized, often clunky scientific software like wgrib2 or Panoply to parse.
Alternatively, .GRB is used for 3D and 2D CAD models by engineering software such as VariCAD and T-FLEX CAD. These are proprietary formats. VariCAD uses a hidden 7z compression structure, while T-FLEX uses a Microsoft Compound container. This creates immediate vendor lock-in; you cannot simply open a VariCAD .GRB file in AutoCAD or SolidWorks without native translation. Finally, the extension is occasionally used for Gerber PCB (Printed Circuit Board) fabrication files, which dictate layout instructions to manufacturing machines.
A common issue with .GRB files is simply identifying which type you have, followed by the struggle to open it without buying expensive or highly niche software. To make the data usable, conversion is almost always required. For weather data, convert GRIB to CSV or NetCDF for data science and spreadsheet analysis. For CAD models, convert to STEP or IGES for 3D interoperability, or PDF for quick 2D visual sharing. For PCB files, convert to SVG or PDF to verify the layout visually. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your GRB file.
Users also converted GRIB, GRB2, GBR, GRIB2, GRS, CDW, ZIP, GRD, TXT, PNG, BTW, PDF and MP4 files.
If you want to convert GRB file to SHP, KML, KMZ, GPX, GEOJSON, TOPOJSON, ECW, SID or DEM, you can use wgrib2 or similar software from the "Meteorological Data & CAD Models" category. In the File menu, look for Save As… or Export….
To convert LAZ, KMZ, DTM, CSV, DEM, PRJ, LAS, GPX, DSM, SHP, DBF or KML files to GRB, try wgrib2 or another comparable tool in the "Meteorological Data & CAD Models" 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 GRB converter.
