this is not possible with JavaScript alone ... should this work on a local machine only or could a server be involved? the second option would open some possibilities, the first might have a chance with a strict IE only solution ... but no cross-browser solution then.
??? please explain exactly what your usecase is ... should the xls-file be connected 'online' to a webpage or should data from a webpage be extracted to a file or what interaction should happen?
i am not using any server. i save the database in teh shared folder and i have excel files which is in different system when they click on a button the data in the excel file should be saved in the shared folder database.
I doubt there is a way to do this, in general browsers do not allow any web-page access to the system as a security measure so there are no commands in Javascript for opening files or opening databases.
Shared folders are asking for either data corruption or a usability problems with users being locked out by other users.
Generally I would recommend you switch to a client server architecture as a more robust overall solution.
