Like other

Unstructured loaders, UnstructuredExcelLoader can be used in both
|
||
|
|
"single" and "elements" mode. If you use the loader in "elements"
|
||
|
|
mode, each sheet in the Excel file will be a an Unstructured Table

element. If you use the loader in "elements" mode, an

"text_as_html" key in the document metadata.
