Markdown Table Generator
A Markdown table generator turns an editable grid into clean GitHub-flavored Markdown. Set the number of columns and rows, type into the cells, choose left, center, or right alignment per column, then copy the result. You can also paste CSV or TSV to fill the grid instantly.
Auto-detects comma or tab delimiter. Quoted fields are supported for CSV.
How Markdown Table Syntax Works
A GitHub-flavored Markdown table is plain text built from three ingredients: pipe characters that mark column boundaries, a header row, and a separator row of dashes directly beneath the header. The separator row is what tells the renderer that the lines around it form a table rather than ordinary paragraphs, so it is never optional.
The three rows
Every table has at least a header row, a separator row, and one body row:
| Name | Role || --- | --- || Ada | Engineer |
The separator must have the same number of columns as the header.
Alignment markers
Colons in the separator row set column alignment:
:---left aligned:---:centered---:right aligned---default (left)
This tool writes these markers for you based on the alignment buttons above each column.
Escaping pipes
A literal pipe inside cell text would be read as a new column. To keep it as text, escape it with a backslash. This generator does that automatically, so typing a|b in a cell produces a\|b in the output and renders as a|b.
Whitespace does not matter
Renderers ignore extra spaces between pipes, so |a|b| and | a | b | are identical. Lining columns up in the raw text is only for human readability; this tool keeps output compact.
Tips for Clean Markdown Tables
- Keep headers short. Long header labels force wide columns that overflow on phones and in chat apps. Abbreviate where you can.
- Right-align numbers. Numeric columns read best right-aligned so digits line up by place value. Use the right-alignment button on those columns.
- Avoid line breaks inside cells. GFM tables do not support multi-line cells. Use a short phrase, or replace a break with a separator such as a semicolon. For rich content, a real list often reads better than a crowded table.
- Watch the column count. Every body row should have the same number of cells as the header. Missing cells render as blanks; extra cells are dropped by most parsers. Editing through the grid keeps the counts in sync automatically.
- Test where it will live. GitHub, GitLab, Reddit, and Obsidian all support GFM tables, but some minimal renderers do not. Preview your table on the target platform before publishing.
- Import instead of retyping. If your data already exists in a spreadsheet, copy the range and paste it into the import box. Spreadsheet copies are tab-separated and import without any cleanup.
Frequently Asked Questions
How do I create a Markdown table?
A Markdown table uses pipe characters (|) to separate columns and a row of dashes to separate the header from the body. The first line is the header, the second line is the separator (one group of dashes per column), and each following line is a data row. This generator builds that syntax for you: type into the grid and copy the output.
How do I align columns in a Markdown table?
Alignment is set in the separator row using colons: :--- for left, :---: for center, and ---: for right. A plain --- defaults to left in most renderers. Click the alignment buttons above each column in the grid and the tool writes the correct markers.
Does Markdown support tables natively?
Tables are not part of the original Markdown spec, but they are part of GitHub Flavored Markdown (GFM) and most modern processors, including GitHub, GitLab, Reddit, Obsidian, and many static site generators. The tables this tool produces follow the GFM standard.
How do I put a pipe character inside a cell?
Escape it with a backslash, writing \|, so the parser does not treat it as a column boundary. This tool escapes pipes in your cell content automatically when it builds the output.
Can I import a CSV or spreadsheet?
Yes. Paste comma-separated (CSV) or tab-separated (TSV) data into the import box and click Import. Copying a range from Excel, Google Sheets, or Numbers produces tab-separated text, which imports cleanly. The grid resizes to fit your data.
Do columns need to line up in the raw text?
No. Renderers ignore extra spaces, so | a | b | and |a|b| produce the same table. Padding cells to form a neat grid is purely for human readability. This tool keeps the output compact while rendering identically.
Why is my Markdown table not rendering?
The usual causes are a missing separator row (the dashes must be the second line), a column-count mismatch between the header and separator, or a blank line between the header and body. Also confirm your platform supports GFM tables; some minimal renderers do not.
Does this tool send my data anywhere?
No. Everything runs in your browser with JavaScript. Your cell content, pasted CSV, and generated Markdown never leave your device. You can disconnect from the internet and the tool works identically.

Privacy & Limitations
- Client-side only. No data is sent to any server. No cookies, no tracking of your cell content or pasted data.
- GFM tables only. Output follows GitHub Flavored Markdown. Single-line cells only; GFM tables cannot contain block-level content such as lists or line breaks inside a cell.
- CSV parsing. Import handles standard comma and tab delimiters with basic quoted-field support. Highly irregular CSV (mixed delimiters, embedded newlines inside quotes) may need manual cleanup first.

Markdown Table Generator FAQ
How do I create a Markdown table?
A Markdown table uses pipe characters to separate columns and a row of dashes to separate the header from the body. For example: | Name | Age | on the first line, | --- | --- | on the second line, then one row per record. This generator builds that syntax for you -- type into the grid and copy the output.
How do I align columns in a Markdown table?
Alignment is controlled by colons in the separator row (the second row). Use :--- for left alignment, :---: for center, and ---: for right. A plain --- defaults to left in most renderers. This tool sets those markers automatically when you pick an alignment for each column.
Does Markdown support tables natively?
Tables are not part of the original Markdown specification, but they are part of GitHub Flavored Markdown (GFM) and most modern Markdown processors, including GitHub, GitLab, Reddit, Obsidian, and many static site generators. The tables this tool produces follow the GFM standard.
How do I put a pipe character inside a Markdown table cell?
A literal pipe inside cell text must be escaped with a backslash, written as a backslash followed by a pipe, so the parser does not treat it as a column boundary. This tool escapes pipe characters in your cell content automatically when it builds the output.
Can I import a CSV or spreadsheet into a Markdown table?
Yes. Paste comma-separated (CSV) or tab-separated (TSV) data into the import box and click Import. Copying a range directly from Excel, Google Sheets, or Numbers produces tab-separated text, which imports cleanly. The grid resizes to fit your data.
Do Markdown table columns need to line up in the raw text?
No. Renderers ignore extra spaces, so | a | b | and |a|b| produce the same table. Padding cells so the raw text forms a neat grid is purely for human readability. This tool does not pad columns, keeping the output compact, but it still renders identically.
How many columns and rows can a Markdown table have?
The Markdown specification sets no limit. In practice, very wide tables are hard to read and may overflow on narrow screens or in chat apps. For large datasets, a dedicated table or a CSV file is usually clearer than a Markdown table.
Why is my Markdown table not rendering?
The most common causes are a missing separator row (the row of dashes must be the second line), a mismatch between the number of columns in the header and the separator, or a blank line between the header and the body. Also confirm your platform supports GFM tables -- some minimal Markdown renderers do not.
Can I edit a Markdown table after I create it?
Yes. Edit any cell directly in the grid and the Markdown output updates instantly. You can add or remove rows and columns at any time, change alignment per column, or toggle the header row on and off without losing your data.
Does this Markdown table generator send my data anywhere?
No. Everything runs in your browser with JavaScript. Your cell content, pasted CSV, and generated Markdown never leave your device. You can disconnect from the internet and the tool works identically.
