We have been using Aspose.cells in an Web application for some years.
Our issue is that we want our users to download information from a Web application to a spreadsheet (about 20 columns and for some users up to 1500 rows with different information in each cell with multiple choices) and then yearly this information shall be updated by a responsible user (2000 different external users)
We don't want the user to change cell/spreadsheet format and it's neccesary that it's validation on each cell, because when the information is updated in the spreadsheet
then we want the user to upload all changes to the very same web application.
We are wondering if Aspose have any software (Aspose.cells og other) or other suggestions to help us solve this kind of problem?
