How to split Excel table into CSV files in .doc by Bold text?

You have 777 .doc files where each .doc file contains a big Excel table, like one here and in Fig. 1. Here, only consider one .doc file. I want to divide the Excel table of .doc file into CSV files by any Unix programming language and/or scripting. I cannot find a way to handle Microsoft fileformats into CSV files. Pseudocode: 1. Extract Excel table from .doc file, which is expanded in the thread How to extract many .doc text + tabular elements into CSV by any Unix tool? 2. Split Excel table (maybe convert here already to CSV) into separate .CSV files by Rule: > *new bolding indicates a new table* i.e. a new CSV file. 3. Apply implicit columns *Location* (bottom/top) and *Date* (dd.mm.yyyy) in the first two lines of the .doc file on the each separate CSV file. Use *Time* column (morning/evening/night). Target files with their columns by Rule 1. Assisstants.csv - Name, Date, Location, Time 2. Other.Assistants.csv - Name, Date, Location, Time 3. General.csv - Event, Date, Location, Time Fig. 1 Example of Excel Table in .doc file OS: Linux Debian Stretch 9 and others Data: .odt file here
