Open GRIB files right in your browser
Drag a .grib or .grib2 file below to explore its variables, preview the grid, and export to CSV, JSON or GeoJSON. Everything runs locally — no upload, no install, no Python.
Why GribBox
A GRIB viewer built for privacy, speed and zero setup.
100% local processing
Your file is decoded by WebAssembly inside your browser and never touches a server — safe for unpublished research and confidential data.
No install, no Python
No HDFView, no wgrib2, no cfgrib/xarray. Just open the page and drop your file.
Works everywhere
Windows, macOS, Linux — even an iPad or a colleague's laptop. If it has a browser, it opens GRIB.
Export anywhere
Turn any variable into CSV, JSON or GeoJSON for Excel, pandas, QGIS or your own pipeline.
