Inherited a messy, unreadable spreadsheet? This 2-hour comprehensive masterclass gives you the complete skill set to audit, debug, and build professional, decision-making formulas in Excel. Whether you're cleaning up someone else's workbook or building complex logic from scratch, this course will transform you from guessing to knowing. 🔍 What You'll Master: Hour 1: Formula Auditing & Professional Workflow Find and highlight all formulas instantly (Ctrl + `). Trace cell dependencies and precedents to map complex models. Convert formulas to values and update ranges in bulk. Debug formulas step-by-step using F9 and the Evaluate tool. Use Range Names for clean, absolute references (no more $ signs!). Build 3D formulas to summarize data across multiple sheets. Hour 2: Advanced Decision-Making Logic IF Function Fundamentals: Automate yes/no decisions. Nested IFs: Handle multiple outcomes (grading, tiering, approvals). IF with AND/OR/NOT: Apply complex, multi-condition business rules. The Modern IFS Function: Replace tangled nested IFs with clean, readable logic (Excel 365). Real-world scenarios: Bonus calculations, tiered pricing, status flags. 📚 Detailed Timestamps / Chapters: 00:00 - Introduction: Taming the Unreadable Spreadsheet 00:01 - Module 1: Formula Auditing Tools 00:08 - Display & Highlight All Formulas (Ctrl + `) 00:20 - Highlight Formulas & Constants with Find & Select 00:44 - Trace Dependents & Precedents to Map Logic 01:17 - Print Dependency Maps for Documentation 01:30 - Use Entire Row/Column References for Dynamic Ranges 01:38 - Module 2: Converting & Updating Values 01:56 - Convert Formulas to Values (3 Methods) 02:42 - Add/Subtract/Multiply Values in Bulk with Paste Special 02:55 - Increase/Decrease Values by a Percentage 03:08 - Module 3: Debugging Complex Formulas 03:14 - Evaluate Formula Parts Step-by-Step with F9 03:52 - Use the Evaluate Formula Tool (Automatic Debugger) 04:04 - Debug Logical (TRUE/FALSE) Formulas 04:15 - Module 4: Range Names for Professional Formulas 04:20 - Create Range Names Instantly (Name Box) 04:45 - Use Range Names in Formulas (Eliminate $ Symbols) 05:05 - Paste a List of All Range Names for Documentation 05:20 - Manage & Delete Names via Name Manager 05:30 - Module 5: 3D Formulas (Summarize Across Sheets) 05:37 - Design Identical Sheet Structures 05:50 - Build 3D SUM Formulas with Shift+Click 06:10 - Applications for Monthly/Regional Reports 06:18 - Module 6: IF Function Foundation 06:25 - IF Syntax & Parameters Explained 06:45 - Real Example: Bonus Based on Job Rating 07:05 - Make Formulas Dynamic with Cell References 07:25 - Module 7: Nested IF Functions 07:35 - Build Nested IFs for 3+ Outcomes (Tiered Logic) 08:05 - Manage Parentheses & Logic Flow 08:25 - Understanding Nested IF Limits 08:40 - Module 8: IF with AND, OR, NOT 08:50 - AND: Require Multiple Conditions 09:25 - OR: Allow Alternative Conditions 10:05 - Combine AND/OR in a Single IF 10:50 - NOT: Exclude Specific Criteria 11:15 - Module 9: The Modern IFS Function 11:25 - IFS Syntax: Clean, Flat Logic 11:50 - Convert a Nested IF Example to IFS 12:10 - Advantages: Readability, Fewer Errors 12:30 - When to Use IF vs. IFS 12:45 - Summary & Your Next Steps ➡️ Continue Your Excel Mastery Journey: Clean Data First: Watch my Power Query Masterclass to automate data preparation. https://www.youtube.com/live/juJBhtSnsx0 Analyze with Speed: Master Pivot Tables to build interactive dashboards in minutes. https://www.youtube.com/live/s-m7JnJBLAU Protect Your Work: Secure files with the Excel Security & Sharing Guide. • Is Your Excel Data Safe?
