We need to update some cells of an Excel file (either xls or xlsx) on an asp.net webpage. The other cells dependent will get updated automatically as well.
We have tried to use: Excel Interop but we have encountered too many problems after developing on the server: installing office, errors with security and adding more rights to the NETWORK SERVICE, … sometimes it works. So it is not stable.
We are looking for an open source library for manipulating an excel file (xls or xlsx) on asp.net. Could you please recommend some good ones?
