Why Markdown Tables Are Painful to Write
The markdown table syntax looks simple until you're actually in it. You need to manually count pipe characters, align separator dashes, and remember the colon positioning for column alignment. A table with ten rows and six columns is fifty lines of tedious formatting.
| Column 1 | Column 2 | Column 3 |
|----------|----------|----------|
| Data 1 | Data 2 | Data 3 |
md0's table generator removes all of that. You build the table visually; the tool writes the markdown.
How to Build a Table
Starting from scratch:
- Open md0.io/to-table
- Click "Add Row" or "Add Column" to set your dimensions
- Type content directly into each cell
- Set column alignment (left, center, right) per column
- Copy the generated markdown
Importing existing data:
- Copy a table from Excel, Google Sheets, or any spreadsheet
- Paste into the import box
- Adjust any formatting
- Copy the markdown output
The import works with tab-separated data, which is what you get when you copy a selection from any major spreadsheet tool.
Column Alignment
Markdown supports three alignment options for table columns. The generator handles the syntax automatically:
| Left aligned | Center aligned | Right aligned |
|:------------|:--------------:|--------------:|
| text | text | text |
| text | text | text |
For most tables:
- Text columns work fine left-aligned (the default)
- Numeric columns should be right-aligned so the digits line up
- Headers or labels sometimes work better centered
Common Use Cases
API documentation tables Endpoint, method, parameters, and description all in one scannable table. Much easier to read than a list of definitions.
README compatibility matrices Node.js version vs OS vs status. The kind of table that would take twenty minutes to write by hand.
Configuration reference tables Option name, type, default value, and description. This is one of the most common tables in technical docs, and it's tedious every time.
Feature comparison tables Plan A vs Plan B vs Plan C across a list of features. The table editor works well for this too, with a spreadsheet-style interface.
What Gets Generated
Here's the markdown output for a three-column table with right-aligned numbers:
| Package | Version | Downloads |
|:------------|:-------:|----------:|
| react | 18.2.0 | 24,000,000|
| typescript | 5.3.0 | 18,000,000|
| next | 14.1.0 | 5,800,000 |
You don't need to know any of that syntax. The tool generates it from your visual input.
Practical Tips
Keep tables narrow. Markdown tables with more than six columns become hard to read on mobile and in terminals. If you have more columns, consider splitting into two tables or using a definition list instead.
Use consistent cell content. Cells with wildly different content lengths produce uneven markdown. It's still valid, but it's harder to read in raw form.
Test in your target environment. GitHub, GitLab, and most documentation tools render markdown tables correctly, but some custom processors don't. Paste your output into the actual context you're using.
For HTML tables to markdown, there's a separate HTML table to markdown converter if you're starting from an existing HTML page.
Export from Spreadsheets
If your data is already in a spreadsheet, there's also a dedicated CSV to table converter and an Excel to table converter. Upload the file directly and get markdown output without the copy-paste step.
Build Your Table
Open md0's table generator and build your first table. No account needed, and the output is clean markdown that works in any renderer.
