Corrupt xlsx after updating

Hello, great lib, I have an issue with the following code whereby the updated file become corrupt. The val you see in code is a string version of a bool so “true” or “false”, I did hardcode a string as val (“hello”), just to see if it was the bool that caused the issue, but the file still got corrupted. Can you please take a look and see what I may be doing wrong, thanks. If I am able to recover the file, it has the updated value, but my app is no longer able to read the file for subsequent parsing

function updateExcelEntry(inputPage,sheet,colKeyIndex,colIndexToUpdate,rowKey,val){
    //console.log("in excel " + inputPage);
    var workbook = new Excel.Workbook();
    workbook.xlsx.readFile(inputPage).then(function() {
            // use workbook
        //console.log("getting sheet " + sheet);
        var worksheet = workbook.getWorksheet(sheet);
        //console.log("getting keyCol " + colKeyIndex);
        var keyCol = worksheet.getColumn(colKeyIndex);
        keyCol.key = "key";
        var col = worksheet.getColumn(colIndexToUpdate);
        col.key = "colToUpdate";

        worksheet.eachRow(function(row, rowNumber) {

            //console.log("checking key val " + row.getCell("key").value);
            //console.log("vs rowKey " + rowKey);
            if(rowNumber !== 1 && row.getCell("key").value === rowKey){
                //console.log("Row " + rowNumber + " = " + JSON.stringify(row.values));
                row.getCell("colToUpdate").value = val;

            }
        });


    }).then(function() {
        return workbook.xlsx.writeFile(inputPage)
    }).then(function() {
        console.log("workbook updated " + inputPage);
    });
}

I solved the problem by using:

https://www.npmjs.com/package/xlsx-populate

All sorts of small formatting problems simply disappeared. I cannot recommend it enough.

I have same issue. After read the latest comments i make a test. Make a simple script that only read and write on different file.

First test:

1. Create new file with LibreOffice
2. run the script
3. file corrupted

Second test:

1. Create new file with Google Docs and download as xlsx
2. run the script
3. works!!

So something is different in LibreOffice/OpenOffice files.
