Is there a formula that will extract the numbers to the left of the cell

Hi there,

I have a column of data in which most of the data is useless it's just how it exports, all I need are the numbers that are to the left of the cell. Is there a formula that will extract only the numbers I need? below is what the column looks like, I've tried to upload an Excel attachment but it won't let me. Any assistance would be greatly appreciated

Try

=LEFT(A1,FIND(" ",A1)-1)+0

Thank you both so much, both worked like a charm

You're welcome

You can also use text-to-columns. Select your data that's in a single column, go to Data, Text to columns, select delimited (next), select space (next), select all but the first column under data preview and click Do not import column, and finish. You can play with it, and keep some of the other columns, such as the dates, if those are useful to you.
