I use UnstructuredExcelLoader to load an Excel file which has the size over 45mb, the process keeps running over 16 hours and seems not to be completed. but when I try to load an Excel file which has the size about 200kb, it finished normally in 5 minutes. I wander whether there is any limit for the langchain loder or not.
My running environment: python 3.10.14, memory: 16Gb
