The T function is used to test whether the value provided is a text.

**Syntax**`=T(value)`

`value`

– The string to test.**Sample Usage**`=T("Rachel Adams")`

*//Returns the value as the output – Rachel Adams.*`=T("8742")`

/*/Returns 8742 as a text string.*

**Sample Google Sheets template with formula here.**

The T function is used to test whether the value provided is text or not. If the value is found to be a text, the T function returns the value as it is, however for any other data type, the T function produces a null string.

- Case 1: Using text as an argument
- Case 2: Using numbers as an argument
- Case 3: Using date or time as an input
- Case 4: Using logical operators or error values as input

Often when collecting data from a survey, some people put in fake data by inputting numbers when asked for their names. The T function in Google Sheets can be used in such situations to filter the data to ensure that only reliable information remains while the fake data is cleared.

The table below summarizes the output that is produced when we use the T function in Google Sheets.

## Formula to use the T function in Google Sheets

The syntax to use the T function in Google Sheets is as follows:

`=T(value)`

The T function takes only one compulsory argument. The argument may represent any manual input or a reference to a cell comprising the data.

In case the argument is a text, the function returns the argument itself otherwise the function returns a blank white cell.

Let’s look at the different types of values and their output when used with the T function in Google Sheets.

**Case 1: Using Text as an argument**

When using text as an argument, the T function returns the text as it is.

The use of “ “ inside the parentheses implies that the value enclosed is in text format. Since the T function checks for text input and returns the text if it’s a string, the value enclosed is produced as output as it is.

**Case 2: Using numbers as an argument**

Number inputs don’t qualify as a string unless they are manually specified so like in the next case. Hence, when using numbers in the T function in Google Sheets, no text is found so the function returns a blank cell as the output.

Sometimes you’ll also find that numbers are inputted as a string in Google Sheets. An easy way to distinguish it would be by noticing the alignment of the data in the cell. If the number is aligned to the left, it’s text input. On the other hand, if it’s not aligned to the left, it’s a number input.

To input a number as text, simply put a single inverted comma (‘) before the value.

What happens when we use a number which is inputted as a text in the T function in Google Sheets? Let’s find out below.

When the numbers are formatted as text, using the T function in Google Sheets returns the number itself in the same format as shown above.

**Case 3: Using date or time as an input**

The T function in Google Sheets considers date and time as numbers hence return a blank cell when used as arguments in the function as shown below.

You can notice that manually inputting the date as time is not accepted when trying to use the T function in Google Sheets and results in the Formula Parse error. To know more about error messages click here.

**Case 4: Using logical values or error values as input**

The T function only recognizes error messages as valid strings of text and displays the same when used. On the contrary, logical values such as true and false are not recognized as text and result in a blank cell when used in the T function.

**Conclusion**

To conclude, the T function in Google Sheets can be a very quick and useful function to use in order to differentiate the text inputs from the non-text ones. The next time you clean the spam data from the surveys make sure to use the T function in Google Sheets.
