XLSX Not Working- Docling Core Needs Update

[ctandrewtran]

Context

Using latest docling-core (v2.6.1) and docling (v2.8.1) xlsx files are unable to be processed due to a ValueError mentioning that the mimetype "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" is not valid as per DocumentOrigin

"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" is not a mimetype offered by default by the mimetype pkg being used by docling and hence has to be added in the extras section

Fix
Add the mimetype as an extra mimetype

Steps to reproduce

Send a .xlsx file as a document stream, then try to do docling.convert()

from docling import *
import streamlit as st
import io

file = st.file_uploader(type=['xlsx'])

arti = docling.pipeline.standard_pdf_pipeline.StandardPdfPipeline.download_models_hf()

pipelinePDF = docling.datampdel.pipeline_options.PdfPipelineOptions(artifacts_path=arti)

converter = docling.document_converter.DocumentConverter(allowed_formats=[docling.InputFormat.XLSX])

buf = io.BytesIO(file.read())

src = docling.datamodel.base_models.DocumentStream(name=file.name, stream=buf) 

doclingified = converter.convert(src)
