How to Improve Microsoft Office Skills

1. Learn advanced Excel: pivot tables, lookup formulas, conditional formatting, data validation, and basic Power Query.

2. Sharpen Word mastery: styles, templates, track changes, section breaks, and headers/footers for long documents.

3. Elevate PowerPoint: slide masters, reusable themes, speaker notes, and clear data visuals instead of crammed slides.

4. Own Outlook: rules, categories, Quick Steps, shared calendars, and focused scheduling.
