Excel’s ability to work seamlessly with both numbers and text is a major strength. But what happens when your data isn’t in the format you need? Numbers stored as text can cause calculation errors. Numeric data displayed as text is vital for certain formats like IDs. This guide makes it simple to convert text to numbers. It also covers converting numbers to text. The guide includes examples and a handy summary table.
Summary Table: Conversions at a Glance
| Conversion | Method | Example | Steps/Formula |
|---|---|---|---|
| Text to Number | Error Indicator | “123” as text to 123 as a number | Click the error icon and select Convert to Number. |
| Text to Number | VALUE Function | “456” → 456 | =VALUE(A1) |
| Text to Number | Multiply by 1 | “789” → 789 | Paste Special > Multiply by a cell containing 1. |
| Text to Number | Change Format | “1000” (stored as text) → 1000 | Change cell format to Number and re-enter values. |
| Number to Text | TEXT Function | 1234 → “001234” (preserve leading zeros) | =TEXT(A1, "000000") |
| Number to Text | Apostrophe | 5678 → “5678” | Type '5678 in the cell. |
| Number to Text | CONCATENATE or TEXTJOIN | 90 → “90” | =CONCATENATE("", A1) or =TEXTJOIN("", TRUE, A1) |
| Number to Text | Change Format to Text | 123 → “123” | Change format to Text and re-enter the values. |
Detailed Techniques with Examples
1. Converting Text to Numbers
Example: Fixing Text Numbers with Error Indicators
- Scenario: You’ve imported data, and numeric values like “500” show a green triangle.
- Solution:
- Select the cells.
- Click the error icon.
- Choose Convert to Number.
- Result: Text “500” becomes a number 500.
Example: Using the VALUE Function
- Scenario: Convert the text value “100” in cell A1 into a number.
- Formula:
=VALUE(A1) - Result: Outputs
100as a number.
Example: Multiply by 1
- Scenario: Your dataset contains “200” as text in multiple cells.
- Steps:
- Enter
1in an empty cell and copy it. - Highlight the text-formatted numbers.
- Go to Paste Special > Multiply.
- Enter
- Result: Converts all text numbers into actual numbers.
2. Converting Numbers to Text
Example: Preserve Leading Zeros in ID Numbers
- Scenario: You want 123 to appear as “000123”.
- Formula:
=TEXT(A1, "000000") - Result: Converts 123 into “000123” as text.
Example: Adding an Apostrophe for Quick Conversion
- Scenario: You want 4567 to stay unchanged visually but become text.
- Steps: Type
'4567(with an apostrophe). - Result: Displays as 4567 but stores the value as text.
Example: Combine Text and Numbers
- Scenario: You need to create a label like “Item-123”.
- Formula:
=CONCATENATE("Item-", A1) - Result: Outputs “Item-123”.
Practical Applications
Formatting Phone Numbers
- Scenario: Display 1234567890 as “(123) 456-7890”.
- Formula:
=TEXT(A1, "(###) ###-####") - Result: Converts the number into a formatted phone number.
Cleaning Data Before Converting
- Scenario: Remove extra spaces or non-printable characters.
- Formulas:
=TRIM(A1)– Removes extra spaces.=CLEAN(A1)– Removes non-printable characters.
- Result: Ensures clean data for accurate conversions.
Pro Tips for Efficiency
- Detect Data Type: Use
=ISTEXT(A1)or=ISNUMBER(A1)to find whether a cell holds text or numbers. - Leverage Power Query: For large datasets, Power Query offers bulk transformations with ease.
- Maintain Formatting: Pre-format columns as Text or Number to prevent unwanted conversions.
