I want to use Galaxy S2 to edit and send excel files I copied from PC HP brand. Can I?

[AC Question]

Before I install SideSync, I want to know if Word, and Excel files can be edited as if I had the office software on my S2.

If you install an app that can edit them. There's no native app (one that comes with any cellphone) that can.
