1. Tellsheet — the cross-platform pick
Tellsheet is a modern Office add-in with 107 tools for cleaning, reshaping, merging, and analyzing data. Because it's built on the current Office platform (not a legacy COM add-in), the same tools run on Windows, Mac, and Excel on the web. Every tool shows an exact before/after preview, and an in-workbook change history lets you revert even after saving. There's a permanent 16-tool free tier, a one-time $39 Pro, and a plain-English AI command bar (bring your own key; only your instruction is sent, never your data).
Best for: mixed Windows/Mac teams, web users, and anyone who wants a preview before changes and a low one-time price.

2. Ablebits Ultimate Suite — the mature Windows heavyweight
Ablebits Ultimate Suite has been refined for years and covers a very broad set of tasks with polished wizards. It's a Windows-only COM add-in, priced one-time from $99 (Personal), $195 (Business), and $495 for a 5-seat license, with a free trial. If you're a Windows power user who wants maximum breadth and doesn't need Mac or web, it's an excellent choice.

3. Kutools for Excel — the inexpensive grab-bag
Kutools packs hundreds of handy utilities at a low one-time price (about $49 lifetime, up to two computers), with a free trial. Like the others here it's Windows-only. If you want sheer quantity of small tools on Windows for as little as possible, it's hard to beat on price.

4. ASAP Utilities — the long-running free-for-home classic
ASAP Utilities has been around for over two decades and bundles 300+ utilities. It's genuinely free for home, personal, and educational use; the Business edition is a one-time $49 (up to three computers per user), Windows-desktop only. A superb, generous option for individuals on Windows.
Best for: home and education users on Windows, and Windows-only teams wanting breadth. Tellsheet vs ASAP Utilities →
