この関数は Google スプレッドシートでも Excel と同じように機能します。構文も引数も同じです。
T(value)The T function is used to return the value if it is text, or an empty string if the value is not text. It is often used in formulas to ensure that a cell contains text, as it ignores numbers, logical values, and error values.
=T("Hello")結果: Hello
Since 'Hello' is a text string, the function returns it.
=T(123)結果:
Since 123 is a number, the function returns an empty string.
It returns an empty string when the input is not text, such as a number, date, or error value.
