Troubleshooting Guide

🚫 Pivot Table Not Updating

Symptoms: New data doesn't appear after refresh

Common Causes:

  • Source range doesn't include new rows
  • Data on different sheet was moved/deleted
  • Filter applied to source data

Solutions:

  1. Convert source to Excel Table (Ctrl+T) for dynamic range
  2. Change Data Source → select entire data including new rows
  3. Use named range with OFFSET formula for auto-expanding

🚫 "Cannot group that selection" Error

When it happens: Trying to group dates or numbers

Root Causes:

  • Blank cells in the column
  • Text values mixed with numbers/dates
  • Dates stored as text

Fix:

=DATEVALUE(A2) // Convert text to date
=VALUE(B2) // Convert text to number

🚫 Numbers Showing as Count Instead of Sum

Why it happens: Excel detects text in number column

Quick Fixes:

  1. Check for leading/trailing spaces: =TRIM(A2)
  2. Remove non-numeric characters: =VALUE(SUBSTITUTE(A2,"$",""))
  3. Use Text to Columns to convert to numbers
  4. Multiply by 1 to force conversion: =A2*1

🚫 Calculated Field Not Working

Common Issues:

  • Field names have spaces (use 'Field Name' with quotes)
  • Division by zero errors
  • Trying to use cell references (not allowed)

Better Formula:

=IF(Units=0, 0, Revenue/Units) // Prevents division errors

🚫 Grand Totals Don't Match Manual Calculation

Check these:

  1. Hidden items in filters (Show all items)
  2. Subtotals being summed in grand total
  3. Custom calculations changing aggregation
  4. Filtered source data not included

Hands-On Practice Scenarios

📊 Scenario 1: Monthly Sales Report

Your Task: Create a report showing sales trends and top performers

Time to complete: 15 minutes

Data Requirements:

  • • Date, Sales Rep, Product, Region, Sales Amount, Units Sold

Success Criteria: Report updates dynamically, shows trends clearly, identifies top performers at a glance

📈 Scenario 2: Year-over-Year Comparison

Challenge: Compare this year vs last year performance

  1. Set up data with at least 2 years of history
  2. Create pivot with Years in columns, Months in rows
  3. Add calculated field for YoY Growth %
  4. Use "Show Values As" → Difference From → Previous Year
  5. Apply color scales to visualize growth patterns
  6. Create a dashboard with multiple year comparisons

Frequently Asked Questions
