How to copy and paste specific information in a same doc using Google App Script? - google-apps-script

Question

I'm very new using GAS what I'm trying to do is to copy some information that is already on the bottom of my doc to anywhere I want in my docs, this should work just by copying the information and paste it at the place I desire, but I want it to be done with Google App Script because it's a daily task and it's easier to do it with a function, instead of copying and pasting manually. Searching on how to do this, I found a lot of information about how to do it on Spreadsheets, but I needed it to be done on Google Docs. How can I do that?
If someone can guide me or send me a link to another similar question that would be very helpful, I don't know where to start.
This is what I have until now, I get all the data of the current doc and set it again to the page, the code gives me problems because it deletes my other information, also it selects all the doc's information. I want to select a piece of specific information and don't copy the content style.
function copyPasteInfo() {
var doc = DocumentApp.getActiveDocument();
var body = doc.getBody();
var notesText = body.getText();
body.appendPageBreak();
body.setText(notesText);
}

If I correctly understood your question, this code will help you to achieve your goal.
let body = DocumentApp.getActiveDocument().getBody();
function moveTable() {
// Get the last table and the previous table found in your Doc
const [previousTable, bottomTable] = getDesireTables();
// Make a copy of your last table
const bottomTableCopy = bottomTable.copy();
// Get the previous table's index
const previousTableIndex = body.getChildIndex(previousTable);
// Insert the last table's copy under the previous table in your Doc
body.insertTable(previousTableIndex + 1, bottomTableCopy);
// Remove the original last table
body.removeChild(bottomTable);
}
function getDesireTables(){
const tablesArr = body.getTables().slice(-3);
// Get the parent element type to check if it's a cell
const parentELementType = tablesArr[tablesArr.length - 1].getParent().getType();
if(parentELementType === DocumentApp.ElementType.TABLE_CELL){
// If there's a table inside a table, return this
return tablesArr.slice(0, 2);
}
else{
return tablesArr.slice(-2);
}
}
What I did was to get the last two tables in the Doc, then I made a copy of the last one and with the index of the previous one, I inserted it under the previous one.
Edit
I noticed you had a table inside a table. therefore I added the getDesireTables function. Which it will check if your bottom table has a table inside.

These are the docs I used to help you:
getTables().
copy().
insertTable(childIndex, table).
