Your office helper · Useful, easy, secure

What is Online Toolbox

Online Toolbox is an independent online tools site, part of a personal easy-office tool series. It is not affiliated with Microsoft in any way. It includes 42 general tools plus VBA, M, and DAX professional sections. VBA, Excel, DAX, M, etc. are registered trademarks of Microsoft. Most tools run locally in your browser; a few (e.g. Office-to-PDF) require server-side processing — files are auto-deleted after 5 minutes.

  • ✅ Local-first: most tools run in your browser; a few need server-side (files auto-deleted in 5 min)
  • ✅ No signup: no account, no cookies, just open and use
  • ✅ No nag: no popups, no QR codes, no cookie banners
  • ✅ More than tools: VBA / M / DAX sections offer a systematic transition path
