"XLS Get Values"is to read Data directly out of a XLS Sheet.
The Smaller Nodes "XLS GetSheetNames", "XLS GetSheetInfos" are additional Nodes which are not essentially.
Everywhere you want to get Data out of an XLS File instead a Textfile.
1. If file Input is wrong the node will do nothing (no crash 🙂 )
2. If the sheet name is wrong it will import first sheet
3. If start/end is empty, it will return the complete sheet.
