On one of our Java application screens, we want to display data loaded from an Excel file on a Excel-like spreadsheet component.
The component has to be able to evaluate the formulas within the spreadsheet and also preserve the general cell formatting as in the loaded Excel file. We have to be able to programmatically change cell values within the spreadsheet.
Being free is a nice-to-have.
Any Java library for that you would recommend?
Apache POI. It’s free
but you cannot evaluate the formalas with the help of this lib.BalusC says that you can. I’ve never tried.JExcel. It’s not free but you can evaluate it for free. It can do all the stuff you’ve described.
