In general, it is possible to import a text file without a time column just by choosing any Sampling Rate from the list in the Text Import Dialog even if this is not the true sampling rate:
=(A1+(1/sampling rate))Where sampling rate is the sample speed / rate of your recorded data in seconds. In this example the original sampling rate of the data file was 512 samples per second.
5. Copy and paste the formula into all remaining cells into Column A.
