I was just wondering if there is a way to paste data from a excel table into a grid in extjs (sencha). Maybe with the ctrl + v option or a way to load the data from the excel too.
You can use the XSLX.js library to read and write XSLX files, and map the resulting javascript objects to records for your grids. However, I am not sure how to combine that external library with Sencha Architect.
