Convert Microsoft Excel (.xlsx, .xls) and Google Sheets spreadsheet data into clean GitHub Flavored Markdown tables. Copy and paste cells directly with live preview.
When you highlight a table in Microsoft Excel or Google Sheets and press Ctrl+C, your operating system does not copy raw binary spreadsheet code.
Instead, it writes Tab-Separated Values (TSV) to your system clipboard. Each horizontal cell is separated by a hidden tab character (\t), and each row ends with a newline (\n). Our converter intercepts this TSV string and automatically converts it into GitHub Flavored Markdown (GFM) tables:
Formulas like =SUM(B2:B10) copy as evaluated numbers rather than raw formula syntax.
Currency signs ($), percentages (%), commas, and dates are preserved cleanly.
Tab stops are converted into vertical Markdown pipes (|) with dynamic column width padding.
In GitHub Flavored Markdown (GFM), column alignments are declared in the second line (the separator row) using colons (:):
| Alignment Type | Separator Syntax | Rendered Output | Spreadsheet Best Practice |
|---|---|---|---|
| Left Aligned | |:---| | Product Names | Text, descriptions, categories |
| Center Aligned | |:---:| | Status / ID | SKUs, dates, status badges |
| Right Aligned | |---:| | $1,250.00 | Currency, metrics, percentages |
Select any table range in Microsoft Excel or Google Sheets and press Ctrl+C (or Cmd+C on Mac), or upload your .xlsx file directly.
Paste into the left box (Ctrl+V). The tool detects tab stops and parses rows instantly.
Choose column alignment (Left, Center, Right), toggle header detection, or click Transpose to swap rows and columns.
Click Copy Markdown to paste into GitHub READMEs, Obsidian notes, Notion, or pull requests.
Document feature comparison matrices, API rate limits, pricing tiers, and dependency requirements directly in repository root files.
Transfer financial models, personal budgets, and project tracking tables into markdown notes without formatting corruption.
Convert sprint roadmaps and benchmark tables for static site generators like Docusaurus, MkDocs, VuePress, and Astro Starlight.
Provide clean tabular data to Large Language Models (ChatGPT, Claude, Gemini) with up to 60% lower token consumption compared to JSON.
Simply highlight any range of cells in Microsoft Excel, press Ctrl+C (or Cmd+C on Mac) to copy, and paste directly into our input box. The tool automatically detects the tab-separated clipboard data (TSV) and converts it instantly into a clean GitHub Flavored Markdown (GFM) table.
Yes! Google Sheets, LibreOffice Calc, Apple Numbers, and web spreadsheets all copy tabular data to the system clipboard in the same standardized tab-separated format, which our converter parses seamlessly without any extra setup.
Yes. You can click the 'Upload .xlsx' button or drag and drop your spreadsheet file. If your workbook contains multiple worksheets, an active sheet selector allows you to choose which tab to convert.
When you copy cells from Excel or Google Sheets, the clipboard receives the computed display values rather than raw formula syntax. This means formatted currency ($1,250.00), percentages (45.8%), dates, and calculated totals are preserved exactly as they appear on your screen.
Use the Alignment dropdown in the top toolbar to choose Left (:---), Center (:---:), Right (---:), or Auto. The separator row of your Markdown table is updated automatically in real time.
Yes, 100%. All parsing, spreadsheet extraction, and Markdown table generation run strictly client-side inside your browser. No files, cell values, or sensitive corporate data are ever uploaded or transmitted to any server.
