Hi Nick,
Thank you for your patience.
At present, there is no component available in web platform to edit documents like Microsoft Word. We have already logged this requirement as feature request. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We request you to visit our website periodically for feature related updates.
Regards,
Sriram P
