Current Retool customer here. We had this concern as well and we're supporting it with a custom component. Retool has been immensely helpful in planning, developing and supporting us in the engagement.
Due to Retool, we've essentially overhauled 60+ 10MB Excel sheets that we had to generate,distribute consolidate for a business planning function into a single app that supports by-user profile settings with 2 guys that are decent Excel/SQL guys but by no means devs.
Strong data grid, and Retool will start eating into "Excel as a front-end" market.
