I saw everyone on here going on and on about raising prices. So I decided to give it a try and raised the prices for all plans on https://sheet2api.com/.
This resulted in a sudden stoppage of new paid customer signups. So just a heads up, that does not always work :)
I will however leave the price change as is, since I'm in this for the long run and think the product is worth the price for the time it saves.
