How to edit files on a computer through the Chrome plugin?

Question

JavaScript

If you write a plugin for Google Chrome, is it possible to give it such rights to edit some files? The plugin itself is something like a calculator, which then saves everything in an xlsx document. It is necessary that he himself save this file on the desktop. Sometimes it is necessary that not a new file be created, but the one that was created should be edited. Is it possible to implement this? If so, how?
