# How Do You Check the Data Type in Google Sheets?

When working with data in Google Sheets, it is important to know the data type of each cell. This information helps us make informed decisions about how to manipulate and analyze our data effectively. In this tutorial, we will explore various methods to check the data type in Google Sheets.

## Using the IS Functions

The IS functions in Google Sheets allow us to check the data type of a specific cell or value. These functions return either TRUE or FALSE based on the data type being checked.

### ISNUMBER Function

To check if a cell contains a numeric value, we can use the ISNUMBER function. It returns TRUE if the cell contains any numeric value and FALSE otherwise.

Syntax:

=ISNUMBER(value)

Example:

• =ISNUMBER(A1)
• =ISNUMBER(42)

### ISTEXT Function

The ISTEXT function is used to determine if a cell contains text. It returns TRUE if the cell contains any text and FALSE otherwise.

Syntax:

=ISTEXT(value)

Example:

• =ISTEXT(A1)
• =ISTEXT(“Hello World”)

### ISDATE Function

If you want to check whether a cell contains a date, you can use the ISDATE function. It returns TRUE if the cell contains a valid date and FALSE otherwise.

Syntax:

=ISDATE(value)

Example:

• =ISDATE(A1)
• =ISDATE(“2022-01-01”)

## Using the TYPE Function

The TYPE function in Google Sheets allows us to determine the data type of a cell or value. It returns a numeric value corresponding to the data type.

Syntax:

=TYPE(value)

Example:

• =TYPE(A1)
• =TYPE(“Hello World”)
• =TYPE(42)

The numeric values returned by the TYPE function are as follows:

• 1 – Number
• 2 – Text
• 3 – Logical value (TRUE/FALSE)
• 4 – Error value
• 5 – Array of values
• 6 – Range of cells

## Conclusion

In this tutorial, we explored different methods to check the data type in Google Sheets. By using functions like ISNUMBER, ISTEXT, ISDATE, and TYPE, we can easily determine whether a cell contains a specific data type. This knowledge is crucial for performing calculations and analysis on our data effectively.

Remember to always verify the data types before applying any specific operations or functions in Google Sheets. This will ensure accurate results and prevent errors in your spreadsheet.
