Sheets Write value on the corresponding line

Okay, let's see if I can explain.

I need to write a value on the line corresponding to the search for a value
For example, I looked for a value in column E, found this value in E13, I need to write a value in F13, how could I do it?

This is not an AppInventor question (unless you are using the Spreadsheet component?), ask on Stackoverflow or check your email for my response to your query from my website.

Through some blocks, using the worksheet ID, I was able to search and return a value in a listview component. I need to write a value in the line corresponding to the search for this value.
For example, I looked for a value in column E, I found this value in E13 inside the listview, I need to write a value in F13, how could I do it?

function doGet(e) {
  var ss = SpreadsheetApp.getActive();
  var sh = ss.getSheetByName('Sheet1');
  var textFinder = ss.createTextFinder(e.parameter.searchTerm).matchEntireCell(true);
  var res = textFinder.findNext();
  if (res) {
  sh.getRange('F' + res.getRow()).setValue(e.parameter.fValue);
  return ContentService.createTextOutput('Match found and row amended');
  } else {
  return ContentService.createTextOutput('No Match found');
  }
}

Does this block belong to any extension?

No, it's AI2's own Spreadsheet component.
