How to make a digital character sheet?

[Thomas Shey]

A spreadsheet is probably the most simple one. You can do it in Excel, but people would need Excel, you can also use LibreOffice Calc, an open source spreadsheet program everyone can download for free on many platforms. Or use Google Sheets (also free, but proprietary), you can easily share it online with people.

You can make interactive PDFs, but that require specialized tools (Adobe Acrobat Pro isn't cheap for example).

It kind of depends on the purpose of why you want to do it. Is it just a tool people use before the in person session or do you want to use it during the session? If so, looking towards a VTT solution might help, and then depending on your VTT of choice (mine is Foundry VTT) it's either impossible or can be quite a bit of work...

You can also have a case where the GM wants to keep copies of sheets and it just is easier if their sheet and the player's is essentially the same format.
