Markdown Table Generator

Build and edit markdown tables with a visual grid

Updated

What is the Markdown Table Generator?

A fast, visual Markdown table editor that works directly in your browser.
Build tables with a spreadsheet‑like grid, set column alignments, enable header rows, and get perfectly formatted Markdown output – instantly.

Whether you need a simple two‑column list or a complex feature matrix for your documentation, this tool removes the friction of manually counting pipes and dashes. Just click to add rows/columns, type your content, and copy the result in one click.

Why this tool?

  • Zero syntax memorization – the grid handles all the formatting for you.
  • Live preview – see the exact Markdown as you type, no guesswork.
  • Alignment control – left, center, right alignment per column with a single dropdown.
  • CSV import – paste data from Excel, Google Sheets, or any CSV source and convert it to a Markdown table instantly.
  • Prettify mode – automatically pads cells so your table source remains readable and neat.
  • Export flexibility – copy Markdown, copy CSV, or download a .csv file for further processing.

No account, and no data leaves your device. It’s entirely client‑side.

How it works

Build your table visually

  1. Start with the grid
    The tool opens with a ready‑to‑use table containing a few rows and columns.
    Click any cell to type your content.

  2. Add or remove rows / columns
    Use the arrow and trash icons next to each row and column to insert or delete elements.
    You can insert rows above/below, columns left/right.

  3. Set header and alignment

  • Toggle Header row on to generate a separator line after the first row.
  • Choose Left, Center, or Right alignment per column using the dropdowns above each column.

  1. Prettify (optional)
    When Prettify output is enabled, the generator will align pipe symbols for a cleaner source view.

  2. Copy or export

  • Use Copy Markdown to grab the formatted table for your docs, README, or issue.
  • Copy CSV or CSV download gives you a comma‑separated version that can be reopened in spreadsheet apps.

Import from CSV

  • Click Import CSV, paste comma‑separated data (including Excel‑copied ranges).
  • The grid instantly populates; alignment can be fine‑tuned afterwards.

Under the hood

The tool transforms the visual grid into a standard | column | column | Markdown table with optional alignment colons (:---, :---:, ---:). Prettify mode pads cells with spaces for perfect source‑level alignment.

All logic is pure client‑side TypeScript; no backend, no network calls.

Frequently asked questions

What is a Markdown table?

A Markdown table is a plain‑text table that uses pipe (|) and hyphen (-) characters to define rows and columns. It’s widely supported in platforms like GitHub, GitLab, Notion, and most static site generators.

How do I align columns?

Use the dropdowns above each column in the visual grid. Choose Left, Center, or Right. The generator will insert the correct colon syntax (:---, :---:, ---:) in the header separator row.

Can I import data from Excel or Google Sheets?

Yes. Copy your data (including headers) from Excel or Sheets, click Import CSV, and paste. The tool automatically parses commas and quoted fields, then fills the grid. Column alignments are set to left initially and can be adjusted afterwards.

Does the generated table work on GitHub?

Absolutely. The output follows the GitHub Flavored Markdown spec. Alignment, headers, and escaping of pipe characters (\|) are all handled correctly for GitHub, GitLab, and most other renderers.

How do I copy the table into my document?

Click Copy Markdown to place the formatted table on your clipboard. Then paste it directly into any Markdown file, README, issue comment, or text editor.

Can I add or remove rows and columns?

Yes. The grid includes arrow and delete icons to insert or delete rows and columns at any position. You can also use the Clear button to reset the table to its initial state.

Is my data stored or sent anywhere?

No. All editing happens entirely in your browser. No data is saved to a server. Your table content stays on your device.

Why does the output have extra spaces (prettify mode)?

Prettify mode aligns the pipe symbols by padding cells with spaces. It makes the raw Markdown easier to read and edit later. You can disable it via the checkbox if you prefer a compact format.
