ForgedAnvil,
First off, let me say that your sheet design is fantastic. As someone who's built many excel based character sheets myself (including working on SpellForge, the spellsheet offshoot of HeroForge) for many different game systems as well as modifying and updating many others for my specific needs, the hardest part for me was always building the actual character sheet design. Making it functional, fully utilizing all the available print/screen space, and making it visually appealing is no small feat (especially working within excel).
Add to that the actual formulations and (I assume, since the file is an .xlsm file) background macro functionality and the fact that the sheet is responsive and cross-platform capable (memories of the last years of HeroForge and the size/performance hit, even after my own rewriting of many of the macros to reduce lines and improve performance) makes it even more impressive.
I was initially going to ask if there's any way to get an unlocked version (or the password to unlock it myself), but I found previous posts through searching that seem to indicate you aren't willing to entertain either option. I totally understand, and don't fault you for it at all. I had hoped to be able to muck with the various tables and lists to modify it to work with a new campaign I'm starting with some tweaked races in it (and to remove any races that aren't available from the drop-down selections), but since the home-brew races can be added via custom, and skipping past the non-used ones isn't a major deal, I can work within the custom offerings.
I do have one issue that I can't see any way around, and that's languages. I see that you made the language data validation cells not list-exclusive, so that manual typing will work, but I really was hoping to simply modify the back-end lists themselves. It's a minor thing, really, but I'm a bit OCD like that.
Regardless, this sheet is an amazing piece of work. Thanks so very much for taking the immense amount of time working on it must involve (knowing how much time I've spent involved in such things myself), and then sharing your work with the world.
