Markdown Table Generator — Convert CSV or TSV to Markdown Table
GitHub READMEs, Notion pages, and Obsidian notes all render pipe-delimited Markdown tables — but writing the pipe syntax by hand means counting dashes for every column. This markdown table generator converts CSV or tab-separated data into a correctly formatted table in one paste: column headers, separator row, and data rows — all pipe-aligned and ready to copy. No signup, no character limit.
What Is Markdown Table Generator?
A markdown table generator converts structured data — rows and columns — into the pipe-delimited table syntax used in Markdown documents, GitHub READMEs, Notion, Obsidian, and any Markdown-compatible editor. Instead of counting pipes and dashes by hand, paste your data and get a correctly formatted Markdown table ready to copy.
Markdown tables require exact alignment of pipe characters and at least three dashes in the separator row between the header and the body. Getting this right manually is tedious for large tables. This tool handles the formatting — you focus on the content.

|-------|-----|------|
| Alice | 30 | NYC |Key Features
Paste comma-separated or tab-separated data — the tool detects the delimiter and builds the table automatically. No format selection or checkbox required.
The required dashes-and-pipes separator row between header and data is generated automatically with the correct minimum three dashes per column — the part most people forget or get wrong.
Output pipe characters are column-aligned in the raw Markdown source for readability — the standard style in well-maintained GitHub READMEs and open-source documentation files.
See the rendered table alongside the raw Markdown syntax to verify column alignment and content before copying. No separate preview step required.
When to Use Markdown Table Generator
Use when adding structured data to GitHub READMEs, documentation sites, Notion pages, or any Markdown-supported platform.
First row is treated as the header. Supports both comma-separated (CSV) and tab-separated (TSV) input — auto-detected.

Common Mistakes & Pro Tips
- !Forgetting that Markdown tables require a separator row of dashes between the header and body — without it, many Markdown renderers will not recognize the table at all and will display it as plain text.
- !Using Markdown tables for data that is better served by HTML tables in a web context — Markdown tables do not support merged cells, multi-line cell content, or complex styling. For complex layouts, write the HTML table directly.
- !Pasting Markdown table output directly into a CMS rich-text editor — most CMS rich-text fields (WordPress Gutenberg, HubSpot, Squarespace) do not render Markdown. They display the raw pipe syntax as plain text. Markdown table syntax only renders where a Markdown parser is active: GitHub, GitLab, Notion, Obsidian, Bear, Jekyll/Hugo static sites, and Markdown-aware CMS fields specifically.
Frequently Asked Questions
Everything you need to know about Markdown Table Generator
Does Markdown table syntax vary between platforms?
+
The basic pipe-delimited syntax (| Col1 | Col2 |) is standardized in GitHub Flavored Markdown (GFM) and supported by most Markdown renderers including Notion, Obsidian, GitLab, and Bitbucket. Column alignment via colons (| :--- | ---: | :---: |) is also widely supported. A few minimal renderers (original Markdown by Daring Fireball) do not support tables at all — always check your target platform.
Can I add column alignment to a Markdown table?
+
Yes. Place colons in the separator row to control alignment: :--- for left, ---: for right, :---: for center. Example: | Left | Right | Center | followed by | :--- | ---: | :---: |. The generated table from this tool uses left alignment by default; edit the separator row to add the colon positioning you need.
What is GitHub Flavored Markdown (GFM) and how does it standardize table syntax?
+
GitHub Flavored Markdown (GFM) is GitHub's extension of the original Markdown specification, standardized in the GFM spec (2017). GFM adds tables, task lists, strikethrough, and autolinks to original Markdown. Tables in GFM require a pipe-delimited header row, a separator row of at least three dashes per column, and one or more pipe-delimited data rows. GFM is the default renderer on GitHub, GitHub Gist, and GitHub Pages. GitLab and Bitbucket use compatible implementations.
How do I add column alignment using colon notation in the separator row?
+
In the separator row, add colons to control alignment: `:---` for left-align, `---:` for right-align, `:---:` for center-align. Example: `| Name | Score | Rank |` followed by `| :--- | ---: | :---: |` produces a table where Name is left-aligned, Score is right-aligned (good for numbers), and Rank is centered. Our tool generates left-aligned separators by default — edit the separator row manually to add the colon positions you need.
What is the minimum valid Markdown table structure?
+
A valid GFM Markdown table requires at minimum: one header row with pipe-delimited cells (| Header1 | Header2 |), one separator row where each cell contains at least three dashes (| --- | --- |), and at least one data row. The pipes on the outer edges are optional but strongly recommended for compatibility. The separator row is mandatory — without it, most Markdown renderers display the rows as plain text instead of a table.
Can I convert a Markdown table back to CSV?
+
Not directly with this tool — this tool generates Markdown from data, not the reverse. To convert a Markdown table back to CSV: remove the pipe characters and separator row manually, or use a dedicated Markdown-to-CSV tool. In Notion, you can select a table and export as CSV. In Obsidian, community plugins can extract Markdown table data to CSV format. For programmatic conversion, libraries like markdown-table-to-csv (npm) or Python's pandas read_fwf approach work well.
How do I create a Markdown table with more than 4 columns?
+
The pipe-delimited syntax scales to any number of columns — just add more cells per row: | Col1 | Col2 | Col3 | Col4 | Col5 |. The separator row must match the column count: | --- | --- | --- | --- | --- |. Wide tables (8+ columns) can become hard to read in the raw source, but most Markdown renderers handle them correctly. If the table is too wide for the page, consider splitting it into two narrower tables or switching to an HTML table for better responsive control.
