Is there a way to create/edit Word/Excel documents using an API, and then allow users to edit them without needing an Office 365 account (using some url based token) ?
My website already give the possibility for users to upload documents, and I would like to add on my website the possibility for users to create documents (word processor and spreadsheet), and give them the possibility to edit them online (like on Office 365).
Is there a way to achieve this with Office 365 API? Or maybe some kind of "offline" API (where all the files are stored on my website)? Or maybe some Open source tool?
