I need to load an excel template file from a folder on the computer (or from a blob), modify some cells, then send this to the client machine, without modifying the original file, and without prompting the user to upload the file.
Currently I have it all working, except for the last part.
Is there a report somewhere that does this that I can use as a reference? Or better yet, a tutorial? I haven't been able to find anything as of yet.
