What Is a Markdown Table Generator?
A Markdown table generator lets you visually design tables using a spreadsheet-like grid and instantly produces the corresponding Markdown syntax. Instead of manually typing pipes, dashes, and alignment colons, you fill in cells and the tool does the formatting for you. This tool runs 100% in your browser — your data is never uploaded to any server.
It supports configurable row and column counts, per-column alignment (left, center, right), CSV/TSV import, live Markdown preview, copy to clipboard, and instant download.
How to Use This Tool
Set Table Size
Use the Data Rows and Columns inputs to set your table dimensions, or click + Row / + Column to add incrementally.
Enter Your Data
Click into each cell and type your content. The first row is always the header. You can also click Import CSV/TSV to paste tabular data.
Set Column Alignment
Click the arrow button above each column to cycle through left, center, and right alignment. The alignment is reflected in the Markdown output.
Copy or Download
Copy the generated Markdown to your clipboard or download it as a .md file. The live preview below shows how the table will render.
Features Explained
Visual Grid Editor
▼
Edit your table in a spreadsheet-like grid. The header row is labeled separately from data rows. Each cell is an editable input field that updates the Markdown output in real time.
Column Alignment
▼
Click the alignment button above any column to cycle through left (←), center (↔), and right (→) alignment. The alignment is encoded in the Markdown separator row using colons (e.g., :---:, ---:).
Add & Delete Rows/Columns
▼
Use + Row and + Column buttons to grow the table, or click the × button next to a row label or above a column to remove it. You can also type exact row/column counts in the number inputs.
CSV/TSV Import
▼
Click Import CSV/TSV to paste comma-separated or tab-separated data. The first line becomes the header row and remaining lines become data rows. The table size adjusts automatically.
Live Preview
▼
A rendered HTML preview of your table appears below the Markdown output, showing exactly how the table will look when rendered in a Markdown viewer or on GitHub.
Copy & Download
▼
Copy the entire Markdown table to your clipboard with one click (shows Copied! for 1.5 seconds), or download it as a .md file.
LocalStorage Persistence
▼
Your table data, dimensions, and alignment settings are automatically saved to your browser's local storage. If you close the tab or refresh the page, your work will be restored.

Tips for Markdown Tables
Use Import for existing data
If you already have data in a spreadsheet, copy it as TSV (tab-separated) and paste it into the Import panel instead of typing each cell manually.
Alignment is per-column
Click the arrow button above each column to set its alignment. Left is default. Numbers often look better right-aligned, and headers often look good centered.
Keep cells concise
Markdown tables are best for short data. For long text, consider using a list or description format instead of a table.
Pipes in cell content
If you need a literal pipe character (|) inside a cell, use the HTML entity | in your Markdown source.
Works with GitHub
The generated syntax is compatible with GitHub Flavored Markdown (GFM), GitLab, Bitbucket, and most Markdown renderers.
Use Clear to start fresh
The Clear button resets the table to defaults and clears saved data from local storage.
Privacy & Security
This tool runs 100% in your browser. Your table data is never uploaded to any server. All generation and formatting happens locally using JavaScript.
Your table data is saved only in your browser's local storage so it persists when you refresh the page. You can clear it at any time using the “Clear” button. No cookies are used, no analytics track your data content, and no third-party services have access to your tables.
