edf2ascii.exe converts all signals in an EDF file to one ASCII table.

The EDF file must have .EDF or .edf as extension, so rename any other extensions.

Open a DOS box in the edf2ascii directory. Then type edf2ascii drive:folder/EDFfilename.
Three ASCII output files are made in the same folder as the EDF file:

- EDFfilename_header.txt  contains the general header of the EDF file.
- EDFfilename_signals.txt contains all signal headers of the EDF file.
- EDFfilename_data.txt    contains all signals.
- EDFfilename_annotations.txt    contains all annotations.

EDFfilename_data.txt contains a separate line for each Sampletime that occurs.
These lines are separated by a linefeed only, so the file does NOT look OK in Notepad: use Wordpad instead.

Each line contains the comma-separated values of the Sampletime and of all Samples that were taken at that time.
Sampletime is expressed in seconds, while sample values are expressed in the Physical dimensions that are specified
in EDFfilename_signals.txt. All values have a dot (.) as decimal separator.

Different sampling frequencies are allowed in the EDF file. In that case, not all signals are sampled at each Sampletime.
Those sample values are simply left empty, but the comma-separator is there.
