WHEN TO USE THIS TOOL
WRITING TECHNICAL DOCS
Your team maintains a pricing matrix or feature comparison in a shared Google Sheet. When it is time to publish that data to a GitHub README or a docs site, copying the cells manually and adding pipes by hand takes forever and introduces typos. Upload the sheet, copy the output, and paste it directly into your Markdown file.
PUBLISHING DATA TO A STATIC SITE
You maintain release notes or a changelog in Excel because non-technical stakeholders update it. Every sprint you need to pull that data into a Markdown-based blog or documentation portal. This converter removes the manual reformatting step between the spreadsheet and your content pipeline.
CONTRIBUTING TO OPEN SOURCE
You are adding a benchmark results table to an open-source project README. Your results are already in a spreadsheet. Rather than counting pipes and dashes to get column alignment right, upload the file and get properly formatted Markdown in one step.
HOW IT WORKS
STEP 1: FILE PARSING
When you upload a .xlsx or .xls file, the tool reads it entirely in your browser using the SheetJS library. Your data never leaves your machine.
STEP 2: HEADER DETECTION
The first row of your selected sheet becomes the column headers in the Markdown table. Each subsequent row maps to a table row. Formulas are exported as their computed values, not the formula text.
STEP 3: MARKDOWN GENERATION
The tool builds valid GFM (GitHub Flavored Markdown) table syntax, including the required separator row of dashes between the header and body. The output is ready to paste into any Markdown editor, README, or docs site.
FREQUENTLY ASKED QUESTIONS
CAN I CONVERT A GOOGLE SHEETS FILE?
Yes. Export your Google Sheet as an Excel file by going to File, Download, Microsoft Excel (.xlsx). Then upload that file here. Alternatively, you can export as CSV and use the CSV to Table converter instead.
WHAT HAPPENS TO MERGED CELLS?
Merged cells do not map cleanly to Markdown table syntax because Markdown tables do not support cell spanning. The tool flattens merged cells, which means only the top-left cell of a merged group retains its value. Unmerge your cells before uploading to get accurate output.
IS MY FILE UPLOADED TO A SERVER?
No. Everything runs in your browser. The file is read locally using the File API and SheetJS. No data is sent to any server, so you can safely use this tool with confidential spreadsheets.
DOES THE MARKDOWN OUTPUT WORK ON GITHUB?
Yes. The output follows GFM (GitHub Flavored Markdown) table syntax, which GitHub renders natively in README files, issues, and pull request descriptions. It also works in GitLab, Notion, Obsidian, and most other Markdown renderers that support GFM tables.
