[SOLVED] Restrict download of excel file

[pgarpgarp]

Hi, I have MS word or excel file and web based application developed on open source (through JAVA, html). I have uploaded word or excel file in this application so that other users can view the file. Any authorised user when clicks on the file, it is downloaded first locally and then opens in MS word or excel. My query is that without is it possible to restrict the download of such file? I want users to view the file in the web browser itself and not download any copy only for viewing purpose. I do not want to use any paid plugins. Else is it possible to have "auto delete" option once viewed by the user.

not possible, not unless you have access to the user browser settings.

No.
Word and Excel loads and uses the Word and Excel applications locally.
Once I've opened it, I can save it locally.

And just about anything visible in my browser...I can copy locally.

You'd have to come up with a completely different presentation layer.

Instead of uploading the Excel file, upload read-only version like PDF.

Thanks all. PDF is one of the solution. But I am not clear on solution from rgd1101 what is about browser settings ? Pl. clarify.

If you present me with an Excel file in my browser, I can save it locally, unless MY browser and PC settings say I can't.
And you cannot influence my browser settings.
