Create a natural language generation software from python

Create a software able to use artificial intelligence to write text from data contained in excel. This program will need to be reusable for different context so I need the ability to map column and tell the software what column is what datatype and what collumns to ignore. How needs to work: 1- I will have some imput data in an excel file, since I will use this software for different purpose, column datatype will vary and I will sometimes have some collumns to ignore Like: A- ID -- ignore B- Vdeo name – ignore C- Primaty KW == primary keyword D- Secondary kw <= secondary keywords (those will always be multiple separated by comma) 2- We never know how many collumns will be in my excel file and I want it on the same excel spreadsheet, I want to select what column should be the output for the text. 3- Text needs to looks like human written and never have the same pattern or template. 4- I will use the generator to write meta descripton so I need to select the average quantity of words or character the text length will be. So its pretty much it, imput from excel, map the collumns, choose an average amount of words and get human generated text in the column I want.
