Extract text from weather data files (GRIB)
To convert GRIB weather files to another format, you need wgrib2 or other Data software.
To convert other file formats to the "Meteorological Data File" file type, you need software like wgrib2 or a similar tool.
A .GRIB file is a Gridded Binary meteorological data file standardized by the World Meteorological Organization (WMO). Meteorologists and weather agencies use this format to store and exchange historical, current, and forecast weather data globally.
These files are highly specialized. They contain multi-dimensional data grids - mapping variables like temperature, wind speed, and precipitation across different latitudes, longitudes, altitudes, and timeframes. Because it is a heavily compressed binary format, you cannot open a .GRIB file using standard text editors or generic spreadsheet software like Microsoft Excel.
Working with .GRIB files is often frustrating for non-meteorologists. Files easily exceed gigabytes in size. You typically need specialized command-line tools like wgrib2 or advanced Geographic Information System (GIS) software like QGIS to read or manipulate the data. If you need to integrate weather data into a standard application, you must convert the file.
The best target formats are CSV for flat tabular data, JSON for web applications, or NetCDF (NC) for scientific modeling. Be aware that converting a multi-dimensional .GRIB file into a 2D format like CSV will flatten the data structure and can generate unmanageably large files.
Standard online converters fail to process .GRIB files because they lack the specific WMO decoding tables required to interpret the binary streams.
Convert.Guru analyzes your GRIB file, detects the exact format, and lets you read the text inside.
Users also converted GRIB2, GRB, NC, GRB2, ZIP, F000, GRID, BZ2, TXT, LVM, TSX, ACSM and SPC files.
If you want to convert GRIB file to NETCDF, CSV, NC, GRIB2, JSON, TIFF, XML, YAML, YML, TOML, INI or CFG, you can use wgrib2 or similar software from the "Meteorological Data Storage" 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 GRIB, try wgrib2 or another comparable tool in the "Meteorological Data Storage" 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 GRIB converter.
