How to check cell values in different sheets using Javascript and ExcelJS

I have a spreadsheet with two sheets. Sheet 1 contains 3 columns with 100s of rows of data (strings). Sheet 2 is to be used as a mastersheet of correct combinations for Sheet 1 to be checked against to make sure the values in in cell are correct. Sheet 2 has 3 columns also.

What I would like to do is loop through sheet 1 row by row, and check each cell's value in the row matches what is in sheet 2, row by row.

If a check fails, then further checks on that row should cease and the next row to be checked commences. Cells in sheet 1 that couldn't be matched should be marked red.

My code below currently isn't looping right and makes way more checks returning true than I think I need/want even just for one check of sheet:1/cell:A against sheet:2/cell:A.

// Import the library
var Excel = require('exceljs');
var moment = require('moment');
// Define Excel filename
var ExcelFile = 'so.xlsx';

// Read from the file
var workbook = new Excel.Workbook();
workbook.xlsx.readFile(ExcelFile)
    .then(function() {
        // Use workbook
        var dataSheet = workbook.getWorksheet('Sheet 1');
        var masterSheet = workbook.getWorksheet('Sheet 2');

        dataSheet.eachRow({ includeEmpty: false }, function(row, rowNumber) {

            var dataSheetCell1 = row.getCell('A').value;
            var dataSheetCell2 = row.getCell('B').value;
            var dataSheetCell3 = row.getCell('C').value;

            masterSheet.eachRow({ includeEmpty: false }, function(row, rowNumber) {

                var masterSheetCell1 = row.getCell('A').value;
                var masterSheetCell2 = row.getCell('B').value;
                var masterSheetCell3 = row.getCell('C').value;

                // Iterate over all cells in a row (including empty cells)
                row.eachCell({ includeEmpty: false }, function(cell, colNumber) {
                    if(dataSheetCell1 == masterSheetCell1) {
                        console.log(true)
                    } else {
                        // Stop all further checks for this sheet(n) row and move onto next row
                        // Mark this failed cell as color red
                    }
                });
            });
        });

        return workbook.xlsx.writeFile('new.xlsx');
    });

Example data would look like this:

Sheet 1:

| COL A | COL B  | COL C  |
|-------|--------|--------|
| bob   | eleven | blue   |
| bob   | eleven | blue   |
| bob   | eleven | red    |
| bob   | eleven | red    |
| bob   | one    | red    |
| bob   | eight  | red    |
| bob   | eight  | red    |
| bob   | eight  | red    |
| terry | seven  | yellow |
| terry | seven  | yellow |
| terry | seven  | gold   |

Sheet 2:

| COL A | COL B  | COL C  |
|-------|--------|--------|
| bob   | eleven | blue   |
| bob   | eleven | red    |
| bob   | eight  | red    |
| terry | seven  | yellow |
| terry | seven  | orange |

According to the sample data, there should be two errors (B5 and C11) that are marked red in sheet 1.
