Google Sheets Macro Language

[Martin Feinstein]

Does anyone know of a way to write a routine in Google Macro language that can check to see if a word is in the dictionary?

As an example, in EXCEL the code below would return a FALSE is word not in dictionary.

Function CheckSpelling(Teststring As String) As Boolean

'

'   Returns True is work in dictionary

'                 False if word not in dictionary

'

    CheckSpelling = True

'

    If Application.CheckSpelling(word:=TempString) = False Then

        CheckSpelling = False

    End If

'

End Function

Thanks.
