   AutoFilter is used to hide rows that don't meet the filter criteria, not delete or change data.

2. Step 2: Compare options with AutoFilter behavior

   Only hiding rows matches what AutoFilter does; deleting or copying data is not automatic.

3. Final Answer:

   It hides rows that don't match your selected criteria. -> Option A

4. Quick Check:

   AutoFilter hides rows = A [OK]

Hint: AutoFilter hides, it never deletes data [OK]

Common Mistakes:

• Thinking AutoFilter deletes rows
• Confusing filtering with copying data
• Assuming AutoFilter changes cell values

3. You have a table with a column "Status" containing values: "Complete", "Pending", "In Progress". After applying AutoFilter and selecting only "Pending", what will you see?

medium

A. The entire table will be copied to a new sheet.

B. All rows will be visible but "Pending" rows highlighted.

C. Rows with "Complete" and "In Progress" will be deleted.

D. Only rows where Status is "Pending" will be visible.

B. Your data contains empty rows inside the range.

C. AutoFilter only works on tables, not ranges.

D. You need to restart Excel to activate AutoFilter.

   AutoFilter dropdowns appear on the selected header row; missing selection causes no arrows.

2. Step 2: Evaluate other options

   Empty rows inside data or restarting Excel do not prevent dropdown arrows; AutoFilter works on ranges too.

3. Final Answer:

   You did not select the header row before applying the filter. -> Option A

4. Quick Check:

   Select header row first = C [OK]

Hint: Always select header row before applying filter [OK]

Common Mistakes:

• Assuming AutoFilter needs tables only
• Thinking Excel restart fixes filter issues
• Ignoring selection step before filtering

5. You have a sales table with columns: Date, Region, Sales. You want to see only sales from "East" region in January 2024. How do you apply AutoFilter correctly?

hard

A. Use the FILTER function in a new sheet with criteria Region="East" and Date in January.

B. Sort the table by Region then manually delete rows not from "East" or January.

C. Apply filter on Region column selecting "East" and on Date column selecting dates from 01/01/2024 to 01/31/2024.

D. Apply filter only on Date column for January; Region filter is not needed.

Solution

1. Step 1: Apply multiple filters to narrow data

   Use AutoFilter dropdowns on both Region and Date columns to select "East" and January dates.

2. Step 2: Eliminate incorrect methods

   Sorting and deleting is manual and risky; FILTER function is different; filtering only Date misses Region filter.

3. Final Answer:

   Apply filter on Region column selecting "East" and on Date column selecting dates from 01/01/2024 to 01/31/2024. -> Option C

4. Quick Check:

   Filter both columns for exact data = A [OK]

Hint: Filter all needed columns to get precise results [OK]

Common Mistakes:

• Filtering only one column when multiple needed
• Deleting rows instead of filtering
• Confusing FILTER function with AutoFilter
