Convert an Excel file to Markdown

Converts an Excel file to Markdown.

Example
This Flow reads a Board Meeting Log (Excel file) from OneDrive, converts it to Markdown, splits the text into chunks, generates embeddings for each chunk, converts the generated vector into a SQL Server-compatible format and stores the text, vector, and document reference in a SQL Server table. This table can then be used for vector search or to feed chat models with the extracted information.

Conversion engines

• Docling provides the most complete extraction and is best for complex Excel files, including multi-sheet workbooks, dense tables, and embedded images. It is the slowest option and can require significant resources for large files. This is currently the only engine that supports image conversion.
• Kreuzberg is a balanced option for larger workbooks. It is typically faster and more resource-efficient than Docling, but may produce less accurate results in complex table structures or heavily formatted sheets.
• MarkItDown is optimized for text-focused and simple tabular content. It is a good choice when speed and clean text output are the top priority, and it uses a custom fine-tuned model.

Returns

This action returns a string/text in Markdown format.
