let's take a look at how we can convert
an older XLS file into a new xlsx format
and we're going to use the Excel 2019
version so let's take a look here we see
that we're in compatibility mode at the
top which means that we don't have all
the features available to us that Excel
2019 offers so if we go down to file we
can click on convert and we just click
on that and it says hey you're just
about to make a change to this file
format and here's the reason for all of
it go ahead and click OK a workbook
conversion completed successfully do you
want to close and reopen the workbook
yes we do and so now it closed the
workbook and reopened it at the top you
can see that we're in the xlsx format
you can also just go to file save as and
then you could choose the xlsx format as
well but the convert button is a little
bit faster
so that's how we convert older format
excel files to xlsx in Excel 2019
