Extract text from E-Merge 2.0 data files (EMRG2)
To convert EMRG2 data files to another format, you need E-Prime or other Data software.
To convert other file formats to the "Psychology Experiment Data" file type, you need software like E-Prime or a similar tool.
The .emrg2 file is an E-Merge 2.0 Data File created by E-Prime, a widely used psychology research software suite developed by Psychology Software Tools. Researchers use this format to combine multiple individual experimental session files (typically EDAT2) into a single, merged data file. This aggregation step is required before performing group-level statistical analysis on behavioral experiment data, such as reaction times and accuracy rates.
This format presents severe limitations for modern data workflows. It is highly proprietary and closed-source. Opening a .emrg2 file natively requires access to E-DataAid, a utility bundled with the expensive E-Prime suite, which often requires a physical USB license dongle and is restricted to Windows environments. As a result, researchers frequently face roadblocks when attempting to share data with collaborators or open archived files on a Mac or open-source operating system.
Because the format is proprietary, standard online converters fail to parse the structured experimental data. To analyze the results in external software like SPSS, R, or Microsoft Excel, you must use the original E-DataAid software to export the file to standard text formats. The ideal conversion targets are CSV or tab-delimited TXT files, which provide universal compatibility without data loss. If our analysis detects a supported underlying or embedded format, viewing or raw data extraction may still be possible.
Convert.Guru analyzes your EMRG2 file, detects the exact format, and lets you read the text inside.
If you want to convert EMRG2 file to , you can use E-Prime or similar software from the "Merged Experiment Data Storage" category. In the File menu, look for Save As… or Export….
To convert files to EMRG2, try E-Prime or another comparable tool in the "Merged Experiment 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 EMRG2 converter.
