Validation

How do I check if all the cells in my data passed the validations or not?

Hey @rakshith.gowdavr

you can call afterValidate hook. If it returns false in the first parameter it means that the validation failed Handsontable example - JSFiddle - Code Playground

If you’d like to get all invalid cells you can use this hook to create an array of those cells or look for cells with the htInvalid class name.
