Can you please provide some more context as to what exactly you are trying to accomplish?
The data you retrieved from Excel is stored in a variable of type data table. You can access a value in a data table by providing indexes like this: %ExcelData1[rowIndex][columnIndex]% where rowIndex and columnIndex are variables storing numeric values. You can also pass the indexes literally - %ExcelData1[0][0]% will return the value at row 1 and column 1 (because indexes are 0-based).
So, if you know which specific cell you want to compare with some other value, you can simply use hard coded indexes, or you can build a loop and loop to generate indexes for you and iterate through the entire table.
