About QDA files

A .qda file is primarily a scientific data analysis and graphing project file used to store raw datasets, 2D/3D plots, and statistical models. It is predominantly associated with specialized graphing software like QtiPlot and KaleidaGraph, though the extension is also used for diagnostic test archives by QIAGEN and qualitative databases by Provalis Research. The biggest disadvantage of the .qda format is its highly proprietary nature. Files are locked into their specific software ecosystems, making collaboration frustrating if the recipient does not own a corresponding, often expensive, software license. Standard online converters routinely fail to process .qda files because they cannot parse the complex, closed-source binary structures or proprietary mathematical rendering engines required to reconstruct the graphs. When extracting data, the most pragmatic target formats are CSV or TXT for raw tabular data, and PDF or SVG for the visual plots. Because this file format is difficult to open or convert, often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format - such as the standard ZIP architecture utilized by QIAGEN medical archives - viewing or conversion may still be possible.

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

Users also converted QLT, QSC and QPC files.

The QDA 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 QDA converter.
