Convert Excel spreadsheets to Markdown tables

Spreadsheets rarely paste cleanly into documentation. Scan Hero converts workbooks with parameters, merged headers, and dense grids into readable Markdown tables — perfect for wikis, static-site docs, and feeding clean context to LLMs and RAG pipelines.

Choose Markdown output, or JSON when you need machine-readable grids. Each sheet becomes its own set of GitHub-flavoured tables.

Example: Excel → Markdown tables

Workbooks with parameters, merged headers, and grids become clean Markdown—ready for docs, wikis, and RAG.

Tip: Merged cells and multi-row headers are flattened into readable Markdown tables. Choose .md output; use JSON if you need machine-readable grids.

Frequently asked questions

What happens to merged cells and multi-row headers?

They are flattened into clean, single-row Markdown table headers so the result renders correctly in any Markdown viewer.

Is this good for RAG and LLM context?

Yes. Markdown tables are compact and unambiguous, which makes them an excellent format for retrieval-augmented generation and agent context.
