Rows in an Excel worksheet can be repeated a specified number of times with the help of a user-defined function. A user defined function can be written to repeat rows a specified number of times. Some knowledge about programming concepts such as if-then-else conditions and do while loops might be necessary to write such a function. The Selection.insert command can be used to insert rows in the worksheet of Excel Office software. There is no need to write the code from scratch as code snippets are freely available for use in worksheets. However, one must ensure that the user-defined function or subroutine to repeat rows a specified number of times is inserted in the right place.
