Inserting variable number of copies of columns based on field data

I have a spreadsheet with about 1600 columns. These columns contain words. I need copies of the columns made based on the field data. e.g. If cell AT7 has two names in it (separated by " / ") and AT9 has three names in it (separated by " / "), I want that column copied and five copies of it inserted ((2 names * 3 names) - the 1 existing column). That's the main part of the task I want done. However, if you can automate the next step, that will be highly desirable. Now that those extra columns have been added in, I'd like each of those 6 columns to have different combination of the names appear. e.g. Cell AT7 contains "æwwɑ / i:zlɑ" and cell AT9 contains "ærnθɑ / here / her", therefore I would like the following data outcomes in a lower row: AT11: æwwɑærnθɑ AU11: æwwɑhere AV11: æwwɑher AW11: i:zlɑærnθɑ AX11: i:zlɑhere AY11: i:zlɑher If that second step can be done, then also the same outcome for AT8 and AT10 cells for AT12:AY12. Happy to clarify further or any any questions. Have attached the document to demonstrate. Note that columns E to AR are a "done by hand" manual processing of what was once Column E's data. So I'm only looking for it to be implemented from Column AS onwards. Important: Please only bid the actual amount you're happy for me to pay you to do the job. If you bid a lower amount in your quote and later ask for a higher amount, we won't be the right fit for each other. Thank you.
