@hajaber , @boyan … Why don’t you use BODA? It’s also free and this last version still works Boda Lite - Multivendor/Multitechnologies Network Management Tool (CM, PM and more)
I use it, and it work perfectly. It’s very quick. (Bonus: it works also for Huawei and Ericsson, so i process all raw CM data from my network into csv files).
