PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
An extremely minimal parser for XLSX (Excel) files
...The input is an XLSX file and the output is a Map<String,String[][]> with key of 'sheet name' and a String[][] of cell data.
Dates are reformatted to dd/MM/yyyy (configurable in the code).
The output of String[][] is to keep the interface compatible with CSV (eg. OpenCSV).
