Repeat rows in Excel: based on cell value, VBA

Rows in an Excel worksheet can be repeated a specified number of times with user-defined functions. The Selection.insert command can be used to insert rows in an Excel sheet and 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.
