Usage Guide
Markdown tables are everywhere in GitHub READMEs, docs and Notion, but pasting from Excel garbles the format completely. This tool converts Excel or CSV data into valid Markdown table syntax (pipe-delimited with alignment markers), local processing with no data leaving the browser.
1. How to use
- Drag .xlsx / .csv files or paste tabular data.
- Auto-detect columns, headers and data rows to produce Markdown table text.
- Choose alignment (left :---, center :---:, right ---:) and copy the output.
2. Markdown table limitations
- Markdown natively does not support merged cells — merged regions are flattened, keeping only the first cell value.
- Tables over 50 columns overflow horizontally on GitHub; consider trimming columns or using HTML tables.
- Alignment markers only work in GitHub/GitLab native rendering — some Markdown renderers ignore them.
- If you also need CSV output, convert Excel → CSV first and preview with csv-visualize.
3. A documentation pipeline for tabular data
In real documentation workflows Excel → Markdown is not the end — generated tables usually need a title (## Table name), description and unit annotations. A efficient pipeline: Excel data prep → this tool for Markdown → manual table notes → markdown-table-to-csv or markdown-table-to-sql to back-convert to other formats. Verify data precision before converting: Excel floating-point display and Markdown text precision can differ, so fix formatting (currency, percentages) in Excel first.
FAQ
