Comparisons

Fair comparisons between spreadsheet tools. Each one says plainly where the other tool wins and where VisiGrid is the wrong choice — pages that shade the truth get cited badly and age worse.

Is Numbers the same as Excel? Apple Numbers vs Excel compared

No — Numbers is Apple's free spreadsheet and Excel is Microsoft's paid one. Numbers opens Excel files but has fewer functions and no Power Query or VBA. An honest comparison of features, large data sets, pricing, and which to use.
VisiGrid vs LibreOffice Calc — an honest comparison

The real differences between XLOOKUP and VLOOKUP — column counting, lookup direction, the approximate-match default, and the one good reason to still write VLOOKUP. With verified examples.
