The entry barcode field is available on custom reports. If you wish to export that field and then convert it to the actual barcode, be sure to download and install the barcode font on your computer (use the Regular file [fre3of9.ttf], not the Extended file [fre3of9x.ttf]): https://www.barcodesinc.com/free-barcode-font/
You may need to experiment with putting an asterisk (*) at the beginning and/or end of the number that represents the barcode in the export.
At this time, the exhibitor barcode field is not available on custom reports.
**Due to the variables involved with installing a font and converting the barcode field in Excel, the FairEntry support team is not able to troubleshoot issues with entry barcodes exported to Excel.
