Convert a file to GDTB

To convert other file formats to the "Econometric Binary File" file type, you need software like gretl or a similar tool.


About GDTB files

The .GDTB file is a binary data container used exclusively by gretl (Gnu Regression, Econometrics and Time-series Library). Economists and statisticians use these files to store large time-series, cross-sectional, or panel datasets. Unlike its XML-based sibling (.GDT), the binary version is designed to load massive datasets quickly. You can open and manipulate these files natively using gretl, an open-source, cross-platform software package for econometric analysis. The main disadvantage of the .GDTB format is its severe lack of interoperability. It is a highly specialized, closed binary format. You cannot open it in standard spreadsheet tools like Microsoft Excel or general text editors. If a colleague sends you a .GDTB file and you use R, Python, or Stata, you are effectively locked out of the data. To share data reliably, you must convert .GDTB files to universal formats like .CSV or .XLSX. Converting to flat text formats will strip away gretl-specific metadata or session configurations, leaving only the raw data columns. Because .GDTB is a specialized binary structure, standard online file converters routinely fail to process it. Often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.

Convert.Guru analyzes your GDTB file, detects the exact format, and lets you read the text inside.

The GDTB 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 GDTB converter.
