Excel conflict list sorting

I'm struggling to do an advanced filter in Excel of our conflict list. There are 12 columns of data and approx 12,500 rows of data.

I am trying to do a custom filter where it will search across ALL rows and columns by a specific name (i.e., Jones). The end result I need is for a condense list that shows me any entry in the spreadsheet that has the text Jones or any name/word that contains Jones.

Right now I can only figure out how to filter on one column but I need to filter across ALL columns and rows.

This is a file I use every day and we spent a lot of time creating it.

Thank you!
