The file is identified by ClamAV as Xls.Dropper.QbotDocu12020-9818439-0, strongly suggesting a Qbot family infection. The XLSX format and the heuristic firing indicate it's a dropper, likely relying on social engineering to trick the user into enabling macros. Once enabled, it would typically download and execute a secondary payload, consistent with Qbot's known behavior.
