How can i read informations from documents content and save these informations in the documents metadata? For example i want to read the content of the cells C2 and automatically save it in the metadata of the file.
Well If you have some extract some fix set of information from certain type of document you need to crate the custom metadata extractor which will do this for you. Out of fox there is nothing you can use because your requirement is very specific. http://wiki.alfresco.com/wiki/Metadata_Extraction
But if you have some extended use cases of this type I think you might need to go for OCR tool integration with Alfresco
