Use Excel to generate a text file

I'm having trouble getting Excel to generate a text file based on the data that I put in. Ideally I would like to create an Excel form that I can fill in and then have Excel spit out a text file (or display the information) for me to then copy and paste it. The information generated will also have html elements.

I'm really stuck on this and not sure where to begin, and I've only used Excel for basic macros in the past so any help is much appreciated!

Thanks.

Apologies, I should have included this beforehand.

Required Output:

HTML Code: 

Inputs That Need To Be Editable:
***May buy multiple / up to X.***
***EXTRA INFO HERE***
****MERCHANT****
XXXcontact detailsXXX
Original values verified XXXXX
***TIME? COURIER? RESTRICTIONS?***

Well, initially I thought it would be good to have the editable inputs in separate cells to the fixed text, but when I tried to copy and paste this into a text document, there were large spaces between words. So now I'm thinking that the best idea would be to have just empty text boxes on display, in which the user can input the relevant data, and then the user can press a "generate" button and Excel will spit out the whole thing.

Currently, I have to manually edit:
***May buy multiple / up to X.***
***EXTRA INFO HERE***
****MERCHANT****
XXXcontact detailsXXX
Original values verified XXXXX
***TIME? COURIER? RESTRICTIONS?***

Then copy and paste the whole thing once I've finished, so the macro ideally would need to just fill in the ***.

If text boxes aren't necessary, I'm very happy to go with your suggestion

A1: May buy multiple / up to X.
A2: EXTRA INFO HERE
A3: MERCHANT
A4: XXXcontact detailsXXX
A5: Original values verified XXXXX
A6: TIME? COURIER? RESTRICTIONS?

So A1-6 will be editable by the user. Then a macro will place the relevant entries into the wider text?

Thanks again for your help JBeaucaire.
