I have 18000 record in excel

We can use EXCEL APPLICATION SCOPE and pass the filepath of the excel file as input especially for the files which have large number of records
As excel is limited to 1,048,576 rows by 16,384 columns
And this can be handled very easily and in faster way as well with EXCEL ACTIVITIES
Only if we don’t have Excel application installed then we can use Workbook activities which has the same set of activities as we have in excel

And it won’t take much time for 18k records and it won’t be more that a min

And once after using excel application scope passing the file path use READ RANGE activity inside the scope and get the output with a variable of type datatable named dt

—now use FOR EACH ROW activity and pass the variable dt as input

For more details on excel limitation in its row count
