I have a file that i uploaded via javascript, and then when i try to getData it says undefined. And when i check it, its empty. But in the table it showing my data from the file.
Cant getData
i upload the data and then convert the data to array of array, when i try to get the data or download via hotInstance its empty. But when i input the data with copy paste it works, no problem happen.
If the data appears it means that is should be available so I think that the issue lays in the declaration of reference to the instance of Handsontable.
I saw that you are using React, so here’s an example that can help https://handsontable.com/docs/react-hot-reference/ It shows how to set up the reference to the hotInstance.
