Supported formats of electronic documents

Electronic documents are the most frequently used computer files. Due to the highly developed modern computer network, it's more convenient to distribute electronic documents than printed ones. Nowadays, a lot of devices are used for document presentation, so there are plenty of proprietary and open file formats. The Document Editor handles the most popular of them.

While uploading or opening the file for editing, it will be converted to the Office Open XML (DOCX) format. It's done to speed up the file processing and increase the interoperability.

The following table contains the formats which can be opened for viewing and/or editing.
