Hi guys, I am currently using a simple offline Excel sheet for KPIs results recording, monitoring, and analysis. unfortunately, this sheet gives me hell since it contains a lot of data which need to be processed, so you can expect all kind of crashing, loosing data, and errors events which drive me crazy. All I need is an offline software that can maintain and process my data. I have surfed the internet and found a lot of online software, but this is not what I seek as I have frequent internet disconnections in my work place. To cut short all this suffering, any recommendations please.
