PHP library for online editing xls\xlsx, doc\docx?

Question

PHP

The situation is this:
The project has a file manager that works with local files (project files). We set the task to add functions for viewing and editing MS Excel and MS Word files. We are currently looking for a solution. And a couple of questions arose:
1 - Does the Google API have such an opportunity? Open and edit files directly in the Google interface, while the files must be stored on our server.
2 - What PHP libraries can you recommend for this purpose? Roughly speaking, the work is planned to follow. scenario: when you go to a file by link, the library scans the file id or url, after which the interface for working with the file opens in a separate tab. Changes in the file (in the file system) must correspond to the changes made by the user in the program interface.
