Spreadsheet Macro Error: Incorrect Array Comparison in Range

Comparing a spreadsheet range with an expected array produces errors. Use this updated function to accurately calculate matching entries:

function evaluateMatches(inputRange) {
  var expectedList = ['X','Y','X','Y','X','Y'];
  var spreadsheet = SpreadsheetApp.getActive();
  var dataMatrix = spreadsheet.getRange(inputRange).getValues();
  var totalMatches = 0;
  for (var i = 0; i < dataMatrix.length; i++) {
    if (dataMatrix[i][0] === expectedList[i]) totalMatches++;
  }
  return 'Matches: ' + totalMatches + ', Total: ' + dataMatrix.length;
}

hey, tried ur code, works pretty well. maybe add errror handlng for multiple columns if needed. cheers!

The code effectively identifies matching entries, but one pitfall I encountered was when the source range differed in row length from the expected array. Implementing a check to ensure both arrays are of equal length helped avoid runtime errors. For instance, if the dataMatrix length is less than the expected array, it could skip the excess values or vice versa. This approach improved debugging in my projects by providing clear error messages. Adjusting for varying array lengths has been practical in dynamic spreadsheets, ensuring robustness in production scripts.
