Hi, I’m Lee, the creator behind the Excel education brand Sheet Leveller.

I specialize in teaching Excel clearly and practically that focuses on understanding patterns rather than memorizing formulas. My work helps everyday Excel users build confidence, avoid common mistakes, and solve real workplace problems more efficiently.

Through my YouTube channel and training materials, I’ve helped thousands of learners enhance their Excel skills by utilizing modern tools such as XLOOKUP, dynamic arrays, and structured thinking.
