Why VBA AutoFit Columns Isn't Working: Common Causes and Solutions

Ever struggled with VBA's AutoFit method stubbornly refusing to resize your columns? You're not alone. While AutoFit is a powerful tool for automatically adjusting column widths to fit your data, it can sometimes act unexpectedly. This article delves into the common reasons why VBA's AutoFit might not be working as intended, providing solutions and best practices for achieving the desired column sizing.

1. Cell Formatting:

Question: "I am trying to use VBA to AutoFit columns in Excel, but it's not working. The code runs without error but the column widths remain unchanged. Any suggestions?"

Answer: (Source: https://stackoverflow.com/questions/15409898/vba-autofit-columns-not-working)

Explanation: One common culprit is inconsistent cell formatting. If a cell contains a formula that results in a very wide or narrow output (e.g., a long string or a very small number), the AutoFit method might adjust the column based on this formula output, not the visible content.

Solution: Before AutoFit, ensure that the cells are formatted appropriately. For example, you might need to adjust the number format to prevent excessive width due to scientific notation or adjust text wrapping if needed.

2. Hidden Rows or Columns:

Question: "I have a macro that autofits columns in a specific range. However, the code only autofits columns in visible rows, ignoring the hidden rows. How can I force it to include hidden rows in the autofit?"

Answer: (Source: https://stackoverflow.com/questions/15459358/vba-autofit-columns-doesnt-work-on-hidden-rows)

Explanation: By default, AutoFit only considers visible cells when adjusting column widths. If your data range includes hidden rows, these will be ignored by AutoFit.

Solution: Before executing AutoFit, make sure all rows are visible. You can achieve this by looping through each row and setting its Hidden property to False.

3. Sheet Protection:

Question: "I have a protected sheet with specific columns locked. When I run AutoFit on the sheet, it does not resize the locked columns. Why?"

Answer: (Source: https://stackoverflow.com/questions/44949990/vba-autofit-columns-in-protected-sheet-excel)

Explanation: Protected sheets restrict changes to their contents, including column widths. This means AutoFit might not be able to resize columns that are locked.

Solution: Before executing AutoFit, you'll need to temporarily unprotect the sheet. After resizing columns, remember to re-protect the sheet for security reasons.

4. Manually Adjusted Columns:

Question: "I previously manually adjusted the column width of some columns in my sheet. Now, when I run AutoFit, it does not resize those columns to fit their data. What's happening?"

Answer: (Source: https://www.excelforum.com/excel-programming/940364-autofit-column-width-does-not-work-in-vba.html)

Explanation: AutoFit respects previous manual column adjustments. If a column has been manually resized, it won't be automatically adjusted by AutoFit.

Solution: If you want to override previous manual adjustments, you can use AutoFit on the entire sheet or a specific range and then manually adjust the column widths of the affected columns again.

5. AutoFit Limitations:

Answer: It's important to note that AutoFit has limitations. It does not consider cell margins, font size changes, or wrapped text when calculating column widths. This means you might still need manual adjustments for optimal appearance after using AutoFit.

Best Practices for VBA AutoFit:

• Clear Formatting: Ensure consistent cell formatting before AutoFit to avoid unexpected results.
• Test Thoroughly: Test your AutoFit code with various data sets and formatting scenarios to identify potential issues.
• Use AutoFit Strategically: Only apply AutoFit to specific columns or ranges where necessary.
• Unprotect Sheets: Temporarily unprotect sheets before using AutoFit on protected sheets.
• Consider Alternatives: For more precise control, explore alternatives like using ColumnWidth property or manual calculations for column width adjustments.

By understanding the common reasons behind AutoFit problems and implementing best practices, you can streamline your Excel automation and achieve the desired column sizing with your VBA code. Remember to test your code thoroughly to avoid unexpected outcomes and optimize the presentation of your data effectively.
