Utilizar comillas dactilográficas dobles (") en fórmulas
Para incluir una cadena de texto en una fórmula, coloque la cadena de texto entre comillas dobles ("), Calc toma los caracteres de la cadena sin intentar interpretarlos. Por ejemplo, la fórmula ="¡Hola mundo!" muestra la cadena de texto ¡Hola mundo! en la celda, sin las comillas dobles envolventes.
La fórmula más compleja =CONCATENAR("La vida es realmente sencilla, "; "pero insistimos en complicarla "; "(Confucio).") concatena tres cadenas individuales entre comillas dobles, dando como resultado La vida es realmente sencilla, pero insistimos en complicarla (Confucio).
Para colocar una comilla doble literal dentro de una cadena en de una fórmula, se pueden usar dos métodos:
-
Puede codificar con «escape» las comillas dobles con una comilla doble adicional; Calc trata las comillas dobles escapadas como un valor literal. Por ejemplo, la fórmula ="Mi nombre es ""Juan Pérez""." genera la cadena Mi nombre es "Juan Pérez". Otro ejemplo simple es la fórmula =UNICODE("""") que devuelve 34, el valor decimal del carácter de comillas Unicode (U+0022); aquí las comillas dobles primera y cuarta indican el principio y el final de la cadena, mientras que la segunda comilla doble escapa a la tercera.
-
Puede usar la función CARACTER o la función UNICAR para insertar una comilla doble. Por ejemplo, la fórmula =UNICAR(34) & "El Guardián entre el centeno" & UNICAR(34) & " es un libro famoso de JD Salinger". muestra la cadena "El Guardián entre el centeno" es un famoso libro de JD Salinger.
Be aware that Calc's AutoCorrect function may modify double quotation marks. AutoCorrect should not change the double quotation marks within formula cells but may change those used in non-formula cells containing text. For example, if you copy a string that is surrounded by some other form of typographical double quotation marks, such as the left double quotation mark (U+201C) and the right double quotation mark (U+201D), and then paste into a formula cell, an error may result. Open the Double Quotes area of the dialog to set the characters used to automatically correct the start and end typographical double quotation marks. Uncheck the toggle button to disable the feature.
Empty string and blank cells
Cells with the empty string ("") are not equivalent to blank cells. When searching or calculating with text, the empty string "" is the text with length zero.
For example, when the formula in A1 returns the empty string "", the following applies:
=ISBLANK(A1) returns FALSE. The cell is not blank.
=ISFORMULA(A1) returns TRUE. The cell is a formula.
=ISLOGICAL(A1) returns FALSE. Not a logical value.
=ISNONTEXT(A1) returns FALSE. The cell has the empty string.
=ISNUMBER(A1) returns FALSE. Not a number.
=ISTEXT(A1) returns TRUE. The cell has the empty string, calculated by a formula.
=LEN(A1) returns 0. The length of the empty string is 0.
