Works bad with documents with non-English locale. We use "," decimal delimiter in Russia. When I use your updated script 1295,84335 becomes 129584335.

@ralphilius Thank you for sharing! I've applied your change and noticed that blank cells become #NUM! error. This can be avoided using Number(data[row][column]) instead of parseFloat(data[row][column]) to do the actual conversion. This works better for me and might be helpful for others as well.
