 1. Included copy of [Mark White's UnZip function](../UnZip.pq).
 2. Both functions (`Excel.Workbook` and `ExcelWorksheetsRowOutlines`) return cells range from worksheet, based on `UsedRange` VBA property (or `dimension` sheet atteribute in SpreadsheetML schema).

+There two files:
+* [`ExcelWorksheetsRowOutlines_TesterDataSet.xlsx`](ExcelWorksheetsRowOutlines_TesterDataSet.xlsx), which contains simple workbook with some rows grouping
+* [`ExcelWorksheetsRowOutlines_Tester.xlsx`](ExcelWorksheetsRowOutlines_Tester.xlsx), which contains code and several queries to show how function works
 
+Download both files, place them somewhere, and write down a full path to the `ExcelWorksheetsRowOutlines_TesterDataSet.xlsx` in the `ExcelWorksheetsRowOutlines_Tester.xlsx ` (see parameter table inside), then refresh loaded query. You can also look on the other possible function results in Power Query Editor.
