Is it possible concurrent editing of xls in addition to GoogleDrive?

Worker in the nth branch is required concurrent editing of a single table. Roughly speaking, the secretaries conduct telephone calls and to the DB to add the value "pozvoleno". At the moment, using Microsoft Office and xls files, which leads naturally to problems of parallelization, because the second opened file can be opened in "read-only". A good way would be Google Drive, but the problem must be a stable Internet connection, which in this location can not be, and when GD turns into a very ordinary office that synchronization will solve problems at the root, i.e., in favor of one or another of the file with the replacement (am I right here?)

Probably would be Feng Office, but:
"At the moment there is a second project for OpenGoo at the University, developed by students Fernando Rodríguez, Ignacio Vázquez and Juan Pedro del Campo.[6] Their project aims to create a free web spreadsheet."(C) Wiki about FangOffice

Of course, there is always remain, but people have to retrain, plus once in red to import already existing databases. Are there alternatives, or is it possible the house is to build GD?

Like the Microsoft office is necessary. You only need to put some server-side components
Sharepoint need.

This question, by the way, on Habre several times asked already. - Delta_Ritchie79 commented on October 3rd 19 at 03:36

Here probably it is necessary to write a backend for synchronization. As a frontend you can use JS libraries
But why write? What are not satisfied with other solutions? Including those that are already in MS-office? - Delta_Ritchie79 commented on October 3rd 19 at 03:38
Don't use MS Office. Because didn't know. Now for me, thanks.
I'm more strelsa to answer the question "are There alternatives, or is it possible the house is to build GD?". - toni commented on October 3rd 19 at 03:41

Let the secretaries directly in the base fraught.
I would in any thread mvc or something else that you know, quickly wrote a frontend to the database.
