with my asp.net mvc application i use reporting tools for generating an automatic report so that users can automaticly get reports from web application. but some users use a excel for establish reports similars of the automatics reports
the problem is that users can create and print reports reflect exactly to data in the database so we can not distinguish between them
the users in past can inputs thier data in excel but since the application is made, the data is displayed automatically without input
i want to know what is the thing that i can learn to put it in automatic database report and can't be put in manuel excel
