Recently, Dahan and co-workers (Dahan, 1991) suggested processing the XRD data by spreadsheet computer programs. Treated in this manner the XRD data became very flexible and made comparison with other data sets, as well as graphical presentation, much easier. In this note a simple FORTRAN 77 program for conversion of PC-APD data files into ASCII files suitable for import into spreadsheets is reported.

In our laboratory XRD data are collected on a Philips 1710 diffractometer operated by the PC-APD version 2.0 (PC-APD Software, 1989). Each experiment usually generates its files containing collected raw intensity data (.RD file), background data (.BK file) and file with peak positions and their intensities (.DI file). The XRD data can be further processed: after smoothing, data are stored in files with extension .SM (.SM file) and, after Kα2 stripping, into files with extension .A2 (.A2 file). All files are stored in the binary format.
