I would like to use custom filters on an Excel datasource. However, the ‘If then’ conditions are only available on the glide table. Please guide!

It doesn’t sound right. You should be available to use computed columns like If-Then-Else on any data sources. Can you attach a screenshot?

I see the option now under, ‘Computed’, ‘If → Then → Else’.  
Thanks for your support!
