谷歌表格导入HTML

Question

I have completed the following script. I want to get a table in my Google Sheet with IMPORTHTML, everything works fine, only if the data changes, then that doesn't change in the Google table. I run the whole thing with a trigger so that will be updated every minute. But here comes the problem, if I let the whole thing run like this and the data changes on the website, and here comes now the problem that doesn't change in the Google Sheet, the old values ​​are simply taken over and over again and not the new ones. If I delete IMPORTHTML from the cell manually and then copy it back in, it works strangely. But unfortunately it doesn't work with the script and the trigger, what am I doing wrong?

function getData() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Lager123");
    
  var importXpath_1 = '=IMPORTHTML("URLwithSIMPLEtable","table", 1)';
  
  sheet.getRange("A1").setValue(importXpath_1);
  
}

Answer 1

Clear the content of the cell and then flush() it before you set the value:

function getData() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Lager123");
    
  var importXpath_1 = '=IMPORTHTML("URLwithSIMPLEtable","table", 1)';
  sheet.getRange("A1").clearContent();
  SpreadsheetApp.flush();
  sheet.getRange("A1").setValue(importXpath_1);
  
}

References:

• clearContent()

• flush()

For not getting cached response in importhtml, we can append some random query parameter in URL string.

var queryString = Math.random(); // This will generate random value
  sheetName.getRange('P7').setValue(queryString); // This random value will be placed in Cell P7

  var cellFunction = '=ImportHtml("URL?"&P7;"table";1)}'; // Value from P7 cell will be appended in URL to avoid caching issue
    sheetName.getRange('A1').setValue(cellFunction); 

I tried this in my project and it's working perfectly.
