The excel file does not have a standard template and i need to find if a keyword exists anywhere in the excel sheet. Headers will not available in these sheets.Please let me know the efficient way to do it and the keyword search should be performed with wild card.
For example, if an excel file has 4 sheets, i have to perform this operation in all 4 sheets. I have used Workbook.GetSheets to get the sheet name and loop through all the sheets. I need to find if any of the cell has keyword and pperform string operation on it.
