Free & Private Online Browser Utility

Visual Markdown Table Generator & Editor

Build, edit, and format Markdown tables visually using a spreadsheet-like grid editor directly in your browser. Configure rows and columns, set column text alignment (left, center, right), import tabular data from CSV or Excel, and copy cleanly formatted Markdown tables. All table formatting runs client-side with zero data uploaded to external servers.

How to use

  1. Step 1: Define Grid Dimensions

    Add or remove rows and columns using the intuitive grid manipulation controls.

  2. Step 2: Enter Cell Data & Alignment

    Type values into cells and select column alignment (left, center, right).

  3. Step 3: Copy Markdown Table

    Click Copy to grab the formatted Markdown text with aligned pipes (|) and hyphen dividers.

Options explained

Column Alignment

Sets alignment syntax in the header separator (:--- for left, :---: for center, ---: for right).

When to use: Use to right-align numeric amounts and center short status tags.

CSV / TSV Import

Parses comma or tab-separated text directly into structured table grid cells.

When to use: Use when copying data from Google Sheets or Excel directly into Markdown documentation.

Prettify Table Columns

Pads cell contents with whitespace so pipe characters align vertically in raw text.

When to use: Use to make raw Markdown source files clean and readable inside code repositories.

Worked example

Input: 2 columns, 2 rows with left-aligned 'Product' and right-aligned 'Price'

Output: | Product | Price: | |:---|---:| | Laptop | $999 |

Formatted according to GitHub Flavored Markdown table specifications.

Tips & limits

  • Right-aligning numeric columns makes financial tables and byte sizes easier to compare visually.
  • Prettified tables with aligned pipe characters make Git diffs much cleaner during code reviews.
  • Use backslash to escape pipe characters (\|) if they appear as literal text inside table cells.

Common problems

Pasted spreadsheet cells do not populate rows properly

Make sure you paste into the CSV import dialog with tab or comma delimiters selected.

Table renders as plain text on GitHub

Ensure you include an empty line before and after the Markdown table block in your document.

Frequently Asked Questions (FAQ)

Can I add line breaks inside a single Markdown table cell?

Standard Markdown tables do not support raw line breaks inside cells; you can use the HTML <br> tag inside a cell.

Is there a limit on table size?

You can build tables with dozens of rows and columns; all grid state is maintained in browser memory.

Does this tool upload my table data?

No. All grid editing, CSV parsing, and Markdown generation run in local browser memory.

Files never leave your device; calculations and transformations happen locally.
