Format every column/row for export to Excel.

Dear Flexmonster Team,

I have developed an export function intended for transferring data to Excel. However, I am encountering an issue where certain column types display values merely as 0s and 1s, while others render as raw HTML.

Is there a method to format each column exclusively for Excel export without affecting the current grid display?
Here is the function:

    private async exportToExcel() {
        const downloadService = this.pbiviz.host.downloadService;

        this.flexmonster.exportTo("excel", { destinationType: "plain", useCustomizeCellForData: false }, async (result: ExportResult) => {

            const base64 = this.uint8ArrayToBase64(result.data);

            const fileName = "myfile.xlsx";
            const fileType = "base64";

            // POWER BI DOWNLOAD SERVICE
            downloadService
                .exportVisualsContent(base64, fileName, fileType, "xlsx file")
                .then((success: boolean) => {
                    if (!success) {
                        console.error(`Failed to download ${fileName}`);
                    }
                });
        });

  }
