FAQ
Does it handle multiple sheets?
Yes. Each sheet in the workbook converts to its own Markdown table in the output, in order.
What about merged cells or formulas?
Merged cells are flattened to plain table cells and formulas convert to their last calculated value — Markdown tables don't support live formulas.
Is this built for AI agents specifically?
Yes. Responses come back as direct text/markdown (not wrapped in JSON), and token-aware headers let an agent decide whether to fetch the full document or a cheaper summary path.
