How this list was made
We separated building a spreadsheet from analysing one, verified non-registry homepages, and were explicit that established platforms like Excel with Copilot lead on heavy analysis while Slaide leads on building a working sheet from your data.
Disclosure: we build Slaide, so we have a stake in this list. We put Slaide first because it is what we would pick for the job above — but every entry names where that tool leads and where it is the wrong choice, ours included, so you can judge the fit yourself.
Example prompt, copy and paste
