I use C# to automate an excel file. I was able to get the workbook and the sheets it contains. If for example I have in sheet1 two cols and 5 rows. I wanted o get the range for the occupied cells as A1:B5. I tried the following code but it did not give the correct result. the columns # and row # were much bigger and the cells were empty as well.
Excel.Range xlRange = excelWorksheet.UsedRange;
int col = xlRange.Columns.Count;
int row = xlRange.Rows.Count;
Is there another way I can use to get that range?
I had a very similar issue as you had. What actually worked is this:
iTotalColumns = xlWorkSheet.UsedRange.Columns.Count;
iTotalRows = xlWorkSheet.UsedRange.Rows.Count;
//These two lines do the magic.
xlWorkSheet.Columns.ClearFormats();
xlWorkSheet.Rows.ClearFormats();
iTotalColumns = xlWorkSheet.UsedRange.Columns.Count;
iTotalRows = xlWorkSheet.UsedRange.Rows.Count;
IMHO what happens is that when you delete data from Excel, it keeps on thinking that there is data in those cells, though they are blank. When I cleared the formats, it removes the blank cells and hence returns actual counts.
