@adamdougal Given that Azure Document Intelligence is used for some of the data loading, and that supports XLSX and PPT already, is there a reason why it's not already supported?

Link to documentation: https://learn.microsoft.com/en-gb/azure/ai-services/document-intelligence/concept-layout?view=doc-intel-4.0.0

Maybe it's not using an up-to-date preview?

@ferrari-leo Heya, I'm not 100% familiar with the history so not sure if that only started to be supported recently. However, given it is now supported, the only thing stopping this, is the priority and time to implement. We always welcome contributions so if you need this feature and have time we'd love a PR :)

@adamdougal I'll have a look at where there'll be free time! But my main point is that if the doc intelligence API already supports analysing the layout of an excel file, then why can I not drag an excel into the ingest data tab and have it processed? I can't pinpoint where in the code it distinguishes between an excel and a pdf to throw the error "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet files are not allowed." In theory there shouldn't need to be more time spent on developing this feature because it's inherent in the doc intelligent API

From memory - I think we were using the old Forms Recognizer API

Hi,

Honestly, Im surprised this is not supported. According to the docs of: https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/data_ingestion.md#supported-document-formats (which seems a less sophisticated version of this repository)

Excel and CSVs are supported.

Looking the code for CSVs:

# These file formats can always be parsed:
    file_processors = {
        ".json": FileProcessor(JsonParser(), SimpleTextSplitter()),
        ".md": FileProcessor(TextParser(), sentence_text_splitter),
        ".txt": FileProcessor(TextParser(), sentence_text_splitter),
        ".csv": FileProcessor(CsvParser(), sentence_text_splitter),
    }

It references the following file.
