I am looking to change text in multiple Word and Excel documents when the document has been opened through my C# application. for example i would have Ccc in multiple Word and Excel documents but would want to change this to an actual company name. the documents
are stored within a folder on the server. I am wondering if there is a way to make this work please?
Many thanks in advance for any help.
Find Word and Excel APIs, learn how to use the APIs by reading the documentation, then design a solution. I used OpenXMLin the past. Be aware there is a learning curve.
