The one thing that has me stuck is the (seemingly arbitrary) 10 row limit. You’re basically asking us to pay take an app pro that hasn’t even been developed yet (and therefore is not making money). The 500 row limit in Google Sheets and Glide Tables is a better solution. Don’t know why you changed it for Excel.
Excel and Airtable are meant to be exclusive to Pro apps. You can connect and try them with a free app, but we want you to upgrade to use them for real.
Our new pricing is coming soon, and will make this much better, as you will upgrade your Team, rather than individual apps, and a Pro team will allow unlimited Airtable & Excel apps.
