Is there a way to just get the CSV data without downloading?

[nurgeldiserikbay]

return result data in function exportToCSV
if in this function some parameter true csv will download, if false just return. true by default

result += rows.join(lineDelimiter);

if (download) this.triggerDownload('data:text/csv; charset=utf-8,' + encodeURIComponent(universalBOM + result), fileName ? fileName : w.config.chart.toolbar.export.csv.filename, '.csv');
else return result
