Quote:1) is it easy to transfer excel sheet to another programming language?
This question cannot be answered without detailed information about what the Excel sheets are supposed to do. If you want the same functionality as Excel, it is better to use Excel directly.
Are height and width limited? Limitations would be e.g. if a page has a fixed size or if the user should be able to extend the table himself. How many elements does a page contain? How many elements are input elements and how many elements are calculated or filled in automatically? Also the question whether the table should be printable would not be unimportant.
In short, as a preliminary work, it will be necessary in any case to describe the scope of work in great detail.
