Converting 1Password 1PUX file to csv with mrc-converter-suite

Hi,
I'm using 1Password for Windows 8.6.0 80600076, im Kanal „PRODUCTION“ on a German Windows 10. After having defined about 50 Objects (Logins, Credit cards, WLAN Routers, Identities..) I've exported all these objects to a 1PUX file, renamed 1PUX to ZIP, unzipped, renamed export .data to data.1pif, and then tried to convert data.1pif to a csv file with the mrc-converter-suite (2021-12-22).

Probably I've not completely understood the command syntax, especially there is no "input file", only an "export file" defined. I hope sombody here can help me to find the correct command syntax. Here is the output in the windows command window:


C:\Users\aesch\Desktop\mrc-converter-suite>perl convert.pl onepif --format csv --debug data.1pif
main : Runninng script from 'C:/Users/aesch/Desktop/mrc-converter-suite'
main : Command Line: onepif --format csv --debug data.1pif
main : Output file: C:\Users\aesch\Desktop\1P_import.1pif
print_fileinfo : Input file info: "data.1pif"
print_fileinfo : size: 192526
