Create Doc files from data entered in gui in windows/linux

the user enters little data, and get big docx file, based on already provided data.

Ex: for meetings documents, the user adds the main titles, fill tables,..etc, and the software make a new Docx file, which includes that data and already made scripts.

the software shall work on Windows, and Linux.

everything in the software shall be easily edited by the user, because he might need to change font scheme or add paragraphs in the future or anything.

the solution should be able to get information from a spreadsheet/document file and manipulate it, then, add it to the Docx file automatically.
