Google Docs supports variables. When a variable is a used in a document, then its value will be inlined where the variable appears.

Is it possible to define transformations on variables, to be applied at use site of the variable? Can we define dependent variables whose values are derived from that of other variables?

For instance, imagine that I have a variable named foo, and that somewhere in the body of my document, I need to print the value of the variable foo in reverse? Is that something that Google Docs supports?

• The method we should use to do this approach by using replaceText and reverse method. – Lime Husky Commented 2 days ago

To make things work we need to use the method replaceText() to replace a text in the document body then using the reverse() method to reverse the text.

Sample Script:

function myFunction() {
  const docs = DocumentApp.getActiveDocument();
  const body = docs.getBody();
  // store your variable names with value here
  const [varOne, varTwo, varThree] = ["foo", "bar", "sample"]

  // reverse the string by converting the it into array by using split and convert it back to string by using join method
  const reverseText = (string) => {return string.split("").reverse().join("")}

  // using replaceText to replace a text in the body
  body.replaceText("{variableOne}", reverseText(varOne));
  body.replaceText("{variableTwo}", reverseText(varTwo));
  body.replaceText("{variableThree}", reverseText(varThree));
}
