Question details

An Excel IF function comparison returns FALSE even when the two numbers being compared appear identical on the spreadsheet.

Fix Excel IF Formula Saying Equal Numbers Are Not Equal

Product: Excel
Device & OS: not provided
Scenario: Using the IF function to compare two numeric values for equality in an Excel workbook.
Observed behavior: The formula evaluates the numbers as not equal, often due to mismatched data types, hidden decimal precision, or floating-point discrepancies not visible through standard cell formatting.

Before you start

Before troubleshooting, widen the columns containing your numbers and increase the decimal places to reveal any hidden precision differences.

Solution 1Recommended

Check and Fix Text Stored as Numbers

Determine if one of the values is formatted as text rather than a number, which causes the IF function to evaluate them as unequal.

Excel treats numeric values and text characters differently. Even if a cell displays '100', Excel might see it as the text string '100'. An IF formula will always return FALSE when comparing a true number to a text string.

Verify data types

Click an empty cell and type =ISTEXT(A1) (replace A1 with your target cell). If it returns TRUE, the value is stored as text. You can also use =ISNUMBER(A1) to verify true numerical values.

Select the text-formatted cells

Highlight the cells that contain the numbers stored as text. You will often see a small green triangle in the top-left corner of these cells.

Convert to Number

Click the yellow diamond warning icon that appears next to the selected cells, and select 'Convert to Number' from the dropdown menu.

Quick Conversion Tip: You can also multiply a text-formatted number by 1 within your formula (e.g., =IF(A1*1=B1, "Match", "No Match")) to force Excel to treat it as a number.

Solution 2

Use the ROUND Function to Fix Precision Errors

Round both numbers to a specific number of decimal places to eliminate microscopic floating-point inconsistencies.

Solution 3

Force Display the Exact Underlying Value

Use a quick text-concatenation trick to bypass cell formatting and see the true value Excel is storing in memory.

Frequently Asked Questions

Why does my IF formula say two identical numbers don't match?

This usually happens because one number is formatted as text instead of a number, or due to hidden decimal places (floating-point precision errors) that make the underlying values slightly different even if they look the same on screen.

Does formatting a cell change its actual value in Excel?

No. Changing the cell format (like reducing the number of visible decimal places or applying a currency symbol) only changes how the number looks. The IF function always compares the exact underlying value stored in memory.

How do I fix a number stored as text so my formula works?

Highlight the affected cells, click the yellow diamond warning sign that appears next to them, and select 'Convert to Number'. You can also use the 'Text to Columns' feature under the Data tab and click Finish without making changes.

Can I use the EXACT function instead of the equals sign for numbers?

The EXACT function is primarily used for text strings and is strictly case-sensitive. While you can use it on numbers, it will still fail if one value is stored as text and the other as a number, or if there are hidden decimal differences.
