The file is an Excel spreadsheet identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', indicating it functions as a dropper. Such files typically rely on social engineering to trick users into enabling macros, which then execute code to download and run a secondary malicious payload. No specific VBA or script content was extracted, but the heuristic strongly suggests a macro-based execution flow.
