Use una función personalizada para obtener la cadena entre comillas dentro de una fórmula de celda.
Código
La publicación externa compartida en el comentario de Yisroel Tech incluye un script que reemplaza cada fórmula en el rango activo por la primera cadena citada en la fórmula correspondiente. La siguiente es una adaptación como función personalizada de ese script.
/**
* Extracts the first text string in double quotes in the formula
* of the referred cell
* @param {"A1"} address Cell address.
* @customfunction
*/
function FirstQuotedTextStringInFormula(address) {
// Checks if the cell address contains a formula, and if so, returns the first
// text string in double quotes in the formula.
// Adapted from https://productforums.google.com/d/msg/docs/ymxKs_QVEbs/pSYrElA0yBQJ
// These regular expressions match the __"__ prefix and the
// __"__ suffix. The search is case-insensitive ("i").
// The backslash has to be doubled so it reaches RegExp correctly.

// does not work correctly with cells that start with '=

// find the prefix
prefixFoundAt = cellFormula.search(prefixToSearchFor);
if (prefixFoundAt >= 0) { // yes, this cell contains the prefix
// remove everything up to and including the prefix
