Definition
Delving right in, the ISTEXT formula in Excel is a handy tool that determines if the value in a cell is text.
Purpose
The purpose of the ISTEXT formula is to validate whether the content of a specific cell is text. This becomes helpful when you’re cleaning data, sorting, or categorizing data based on its type.
Syntax
The syntax for the ISTEXT formula is straightforward and easy to remember:
=ISTEXT(value)
Parameters
The ISTEXT formula only requires one parameter – ‘value’. This is the content you’re checking to see if it’s text.
Returns
ISTEXT will return TRUE if the ‘value’ is text, and FALSE if it’s not.
Usage notes
ISTEXT is a versatile tool in Excel that can be used alone or in conjunction with other functions to enhance your data analysis capabilities.
Availability
The ISTEXT formula is available across all versions of Excel, making it a universally applicable function.
Example #1
For our first example, if cell A1 contains the word ‘Excel’, the formula:
=ISTEXT(A1)
will return TRUE, because ‘Excel’ is a text string.
Example #2
In our second example, if cell B1 contains the number 10, the ISTEXT formula:
=ISTEXT(B1)
will return FALSE, as 10 is a number, not a text string.
Example #3
Let’s say cell C1 contains the date ‘1/1/2022’. Then, the ISTEXT formula:
=ISTEXT(C1)
will return FALSE, as Excel treats dates as numbers behind the scenes.
Example #4
In this example, suppose cell D1 contains a formula, ‘=SUM(E1:E5)’. The ISTEXT formula:
=ISTEXT(D1)
will return FALSE, as the content of D1 is a formula that results in a number.
Example #5
In our final example, if we have an empty cell E1, the ISTEXT formula:
=ISTEXT(E1)
will return FALSE since an empty cell is not considered text.
Tips and tricks
Combine ISTEXT with other functions like IF, to create dynamic formulas that respond to data types.
Limitations
ISTEXT only checks if a value is text. It doesn’t validate the text or check its length.
Common errors and solutions
A common error is not understanding Excel’s data type definitions. For example, dates are not considered text by Excel.
Best Practices
It’s best to understand your data types well when using ISTEXT. Also, combine it with other Excel functions for more complex data analysis.
List of Related functions
ISTEXT is related to other Excel functions like ISNUMBER, ISNONTEXT, ISLOGICAL, ISERROR, and ISNA.
Frequently Used with the formulas
ISTEXT often gets paired with IF and VLOOKUP functions to create dynamic formulas.
Frequently Asked Questions

ISTEXT can handle named ranges, but it will return FALSE unless the named range consists entirely of text cells.
Q. Does ISTEXT return TRUE for numeric text?
Yes, ISTEXT will return TRUE if the cell contains numeric values entered as text.
Q. Can I use ISTEXT to check if a cell contains text and numbers?
ISTEXT checks the data type of the entire cell content. If a cell contains both text and numbers, ISTEXT will return TRUE.
Q. Does ISTEXT return TRUE for an empty cell?
No, an empty cell is not considered a text and ISTEXT will return FALSE.
Q. Can ISTEXT return an error?
No, ISTEXT always returns either TRUE or FALSE. It doesn’t return any error values.
