Excel Data Not Sorting Correctly? Fix

Your Excel data is sorting incorrectly, numbers appear out of order, rows break apart, dates sort randomly, or filters don’t behave properly.
This usually happens because of inconsistent data types, hidden formatting issues, merged cells, or incomplete range selection.

Why the Issue Happens

• Numbers stored as text
• Mixed data types in the same column
• Hidden spaces or non-printable characters
• Blank rows or columns breaking the dataset
• Only part of the table selected before sorting
• Merged cells interfering with sort logic
• Dates stored as text instead of actual dates
• Hidden filters or old sort settings

Step-by-Step Fixes

Step 1: Select the Entire Dataset

Sorting only one column can break row alignment.

Wrong:

• Selecting only Column A before sorting

Fix:

• Select the full table before sorting

Shortcut:

Ctrl + A

Then apply sorting.

Step 2: Convert Numbers Stored as Text

If numbers sort like:

1
10
100
2
20

they are stored as text.

Check:

=ISNUMBER(A1)

If FALSE → convert them.

Fix:

=VALUE(A1)

Or:

1. Select column
2. Data → Text to Columns → Finish

Step 3: Remove Hidden Spaces

Extra spaces disrupt alphabetical sorting.

Fix:

=TRIM(A1)

For imported data:

=CLEAN(A1)

Use helper columns if needed.

Step 4: Fix Date Sorting Problems

Dates stored as text sort incorrectly.

Wrong sort example:

01-Jan
02-Feb
15-Dec

appearing randomly.

Check:

=ISNUMBER(A1)

Real dates return TRUE.

Fix text dates:

=DATEVALUE(A1)

Then format as Date again.

Step 5: Remove Blank Rows and Columns

Blank rows break sorting ranges.

Fix:

• Delete completely blank rows
• Ensure the dataset is continuous

Excel sorts more reliably with uninterrupted tables.

Step 6: Unmerge Cells

Merged cells frequently cause sorting failures.

Fix:

Home → Merge & Center → Unmerge Cells

Then fill missing values properly.

Step 7: Clear Old Filters and Sorts

Hidden filters can interfere with new sorting.

Fix:

Data → Clear

Then reapply sorting.

Step 8: Use Excel Tables

Excel Tables handle sorting more reliably than raw ranges.

Convert dataset:

Ctrl + T

Benefits:

• Automatic filter handling
• Dynamic sorting
• Better range management

Step 9: Check for Mixed Data Types

A single column should contain only one data type.

Bad example:

100
200
N/A
300
Text

Mixed types cause unstable sorting.

Fix:

• Separate text labels from numeric columns
• Standardize formatting

Step 10: Sort Using Custom Options

For advanced sorting:

Data → Sort

You can sort by:

• Values
• Cell color
• Font color
• Multiple levels

Useful for financial reports and dashboards.

Common Mistakes

• Sorting only one column instead of the entire table
• Keeping numbers stored as text
• Ignoring hidden spaces
• Leaving merged cells in datasets
• Mixing dates, numbers, and text in one column
• Forgetting to clear old filters

Pro Tips

Use Excel Tables for all professional datasets

Use helper columns to clean imported data before sorting

Standardize formats before analysis

Use TRIM and CLEAN regularly on imported datasets

Avoid merged cells completely in analytical workbooks

Bottom Line

Fix sorting issues in this order:

1. Select the full dataset
2. Convert text to proper numbers/dates
3. Remove spaces and blanks
4. Unmerge cells
5. Use Excel Tables for structured sorting

Most Excel sorting problems are caused by inconsistent data formatting, not the sorting feature itself.
