Introduction to ISTEXT in Excel
Trying to figure out if a cell contains text instead of a number or formula? 🔠 That’s where the ISTEXT function in Excel shines. Whether you’re cleaning up survey data, validating form entries, or organizing reports, ISTEXT helps you instantly identify which cells contain text-based content — no guesswork needed.
Let’s break down exactly how ISTEXT works, when to use it, and how to maximize its utility across any platform.
What Is the ISTEXT Function?
The ISTEXT function is a logical test that checks whether a value in a cell is text. It returns:
TRUEif the cell contains textFALSEif the cell contains anything else (number, date, blank, error)
📌 It’s part of Excel’s Information Functions, used for quick data-type checks.
Syntax of ISTEXT
=ISTEXT(value)
- value: This can be a direct input, a cell reference, or a formula result.
Example:
=ISTEXT(A1)
This checks whether the value in A1 is text and returns either TRUE or FALSE.
What ISTEXT Returns
| Cell Value | Formula | Result |
|---|---|---|
"Apple" | =ISTEXT(A1) | TRUE |
123 | =ISTEXT(A2) | FALSE |
=“Yes” | =ISTEXT(A3) | TRUE |
#N/A | =ISTEXT(A4) | FALSE |
"" (empty) | =ISTEXT(A5) | FALSE |
✅ ISTEXT checks whether text is present, even if generated by a formula.
ISTEXT vs ISNUMBER vs ISNONTEXT
| Function | Returns TRUE if… |
|---|---|
ISTEXT() | The value is text |
ISNUMBER() | The value is a number |
ISNONTEXT() | The value is not text |
ISTEXT is your go-to for detecting labels, words, or strings in your cells.
Common Use Cases for ISTEXT
- ✅ Validating form responses (e.g., name or email fields)
- 🧹 Cleaning imported data to filter only text entries
- 📊 Survey analysis to separate qualitative vs quantitative input
- 📋 Checking cells for errors or conversion issues
Using ISTEXT with Cell References
To dynamically test cells:
=ISTEXT(B2)
When applied across a range, it helps you audit large datasets for text presence.
ISTEXT with IF Statements
Add logic for text-based cells:
=IF(ISTEXT(A2), "Text Found", "Not Text")
Ideal for:
- Flagging bad inputs
- Creating custom labels
- Directing formulas based on content type
Using ISTEXT with Conditional Formatting
Highlight cells with text:
- Select your data range
- Go to Home > Conditional Formatting > New Rule
- Choose: “Use a formula”
- Enter:
=ISTEXT(A2) - Choose a formatting style (e.g., blue fill)
📘 Now, all text cells are visually distinguished!
Filtering Text Values Using ISTEXT
- Add a helper column:
=ISTEXT(A2) - Fill down
- Apply a filter → Select only
TRUE
This isolates text-only rows for targeted edits or exports.
Nesting ISTEXT in Larger Formulas
Combine with AND, OR, or SEARCH:
=IF(AND(ISTEXT(A2), ISNUMBER(B2)), "Text + Number", "Mismatch")
This enhances your logic for complex data validation models.
ISTEXT for Data Validation
To allow only text inputs:
- Select the range
- Go to Data > Data Validation > Custom
- Use:
=ISTEXT(A1)
Users entering numbers or formulas will be blocked 🛑.
Handling Blank Cells and Errors
ISTEXT returns FALSE for:
- Empty cells (
"") - Errors like
#VALUE!or#N/A
🔍 Tip: Combine with IFERROR() or ISBLANK() for smarter results.

ISTEXT for Surveys, Forms, and Reports
📋 Use ISTEXT to:
- Validate text-based answers in surveys
- Check name fields aren’t left empty or numeric
- Flag “Other” responses for manual review
- Build smart formulas that adjust automatically
Avoiding Common Mistakes with ISTEXT
| Mistake | Fix |
|---|---|
| Applying to whole columns | Use specific ranges for speed |
| Misinterpreting blanks | Use ISBLANK() with ISTEXT |
| Ignoring error values | Use IFERROR() or ISERR() |
✅ Always test formulas with sample inputs before applying to full datasets.
