Hi everyone,

Currently I am having missing data issue after I export the json data into the csv file.

This is the first time it happens. Please refer to picture below:

And the JSON response looks like below:

My logic looks like below:

JSON - Excel data mapping and manipulation:

function DataForReport2(apiData) {
    let reportData = apiData.map(data => ({
        HERO_CASE_ID: data.HERO_CASE_ID,
        CUSTOMER_NAME: data.CUST_NAME,
        DESCRIPTION: (data?.DESCRIPTION ?? '').replaceAll('\n', '<br>').replace(/^[-]/, "'-"),
        HERO_LOGGER: data.HERO_LOGGER,
        HERO_LOGGER_ID: data.HERO_LOGGER_ID,

        GROUP: data.GROUP_,
        SR_NUM: data.SR_NUM,
        TT_NUM: data.TT_NUM,
        UPDATE_REMARKS: (data?.UPDATE_REMARKS ?? '').replaceAll('\n', '<br>').replace(/^[-]/, "'-"),

        AGING_UNASSIGNED: data.AGING_UNASSIGNED,
        DATE_UNASSIGNED: (data?.DATE_UNASSIGNED == null) ? moment(data.DATE_UNASSIGNED).format('DD/MM/YYYY h:mm:ss a') : null,
        AGING_ASSIGNED: data.AGING_ASSIGNED,

        CKC_NUM: data.CKC_NUM,
        EXT_SYS_REF: data.EXT_SYS_REF,
        STAKEHOLDER_REF: data.STAKEHOLDER_REF
    }));

    return reportData;
}

UI Logic

`const getReport = async (type) => {
await DashboardService.dailyReport(enqueueSnackbar, closeSnackbar, token, type).then(res => {
console.log(res.data.message);

        if (res.status !== 200) return;
        let getFilename = (type) => {
            if (type === 'daily') return 'HERO-DAILY-REPORT.csv'
            if (type === 'weekly') return 'HERO-WEEKLY-REPORT.csv'
            if (type === 'current-month') return `HERO-MONTHLY-REPORT(${moment().format('MMMM')}).csv`
            if (type === 'last-month') return `HERO-MONTHLY-REPORT(${moment().subtract(1, 'months').format('MMMM')}).csv`
            if (type === 'last-3-month') return `HERO-MONTHLY-REPORT(${moment().subtract(3, 'months').format('MMMM')} - ${moment().format('MMMM')}).csv`
            if (type === 'last-6-month') return `HERO-MONTHLY-REPORT(${moment().subtract(5, 'months').format('MMMM')} - ${moment().format('MMMM')}).csv`
            else return 'HERO-REPORT.csv'
        }
        // const rows = DataForReport(res.data.message);
        const rows = DataForReport2(res.data.message);
        const fileName = getFilename(type);

        // create workbook and worksheet
        const workbook = XLSX.utils.book_new();
        const worksheet = XLSX.utils.json_to_sheet(rows, {range:1});

        XLSX.utils.book_append_sheet(workbook, worksheet, "Reporting");

        XLSX.writeFile(workbook, fileName)
    })
}`

Please not that this logic is in React JS project.

@Aiman1017 we have exeactly the same problem, also with exporting to xlsx workbooks. Is it also for you that this error is only happening since a few days/ hours?

Thank you for joining the chat and helping diagnose the issue!

This is a Chromium bug.

Reproduction:

function make_obj() {
  var obj = ({});
  for(var i = 0; i < 4000000; ++i) obj[i + " " + i] = {idx: i};
  obj["!ref"] = 3;
  console.log(obj["!ref"]);
  return obj
}

var data = { Sheets: {}}; data.Sheets["abc"] = make_obj(); console.log(data.Sheets.abc["!ref"]);

This issue seems to be sensitive to the number of properties in the object

We will reopen this issue and re-close once Google fixes the bug.

This issue has been reported to Chromium: https://issues.chromium.org/issues/390568195

In the interim, force dense-mode worksheets by passing dense: true to json_to_sheet or read or other methods.

Hello there Sheetjs Team,

Noted but I have solved the issue by moving the logic from Front-end portal to the Back-end server to resolved this issue as a temporary workaround.

When I am free, I'll try to add the "dense" property in my testing.
