Cellfig alternatives

This is the most revolutionary app I've used for my elementary school's data management. Easy to use and incredibly powerful and flexible. The learning curve is minimal for the non-engineers in my team. They're used to Excel and Sheets so they don't have to learn a whole new UI to see and search data. The devs in the team have access to the API so we've been able to integrate it seamlessly into our Customer Portals so that the backend is basically a collection of Google Sheets while the front end is a full-featured Web App. What a revolution this has been!

Excellent feature for validate and fix excel format and data issues, before user upload data to out system. Before I was validate user excel only header, and report value format or empty errors when exact row is parsing, and throw an error message tell user which row and column data is wrong, the plain error message is painful for user to read and understand and to fix data error. OneSchema could show and fix errors visually which is great great user experience improvement！
