# Loop Sheet flows

If a flow contains a [Loop Spreadsheet Rows](/reference/browserflow-commands/spreadsheet/loop-spreadsheet-rows.md) command, Browserflow Cloud will create a separate run for each row in the loop.

For example, if a flow loops through a spreadsheet to visit 10 different URLs and scrape each of them, Browserflow Cloud will create 10 runs that each scrape a single URL rather than a single run that scrapes 10 URLs.

Since each run is limited to 2 minutes of execution, this design allows processing spreadsheets with many rows by giving 2 minutes of execution to each row rather than timing out by trying to execute all the rows within the time limit.
