The ISTEXT function in Excel is used to check if a cell contains text. It returns TRUE if the cell contains text, and FALSE if it does not. This function is particularly useful when you need to validate data or perform conditional operations based on whether a cell contains text.

Syntax:

ISTEXT(value)

• value: The value or cell reference you want to check.

Example 1:
If cell A1 contains the text “Hello”, the formula =ISTEXT(A1) will return TRUE.

Example 2:
If cell A2 contains the number 123, the formula =ISTEXT(A2) will return FALSE.

Use Cases:

• Data validation: Ensure that a cell contains text before performing further operations.
• Conditional formatting: Highlight cells that contain text.
• Error checking: Identify cells that should contain text but do not.

Notes:

• ISTEXT only checks for text values. Numbers, dates, and logical values (TRUE/FALSE) will return FALSE.
• If the cell is empty, ISTEXT will return FALSE.
