Table to Markdown Converter
Convert HTML tables, CSV data, or TSV files into properly formatted Markdown tables with aligned columns. Paste your data, adjust column alignment, and get clean Markdown output instantly.
如何使用
Select your input format (HTML, CSV, or TSV) and paste your table data. The tool parses the input and generates a Markdown table with proper column padding. Use the alignment toggles to set left, center, or right alignment per column. Toggle compact mode for minimal output without padding spaces.
特征
- Three Input Formats – Paste HTML tables, CSV data (RFC 4180 with quoted fields), or tab-separated values
- Aligned Output – Columns are padded to equal width for clean, readable Markdown
- Per-Column Alignment – Toggle left, center, or right alignment for each column independently
- Compact Mode – Strip padding for minimal Markdown output when space matters
- 实时预览 – See your Markdown table rendered as HTML below the output
- Edge Case Handling – Escapes pipe characters in cell content, handles empty cells and special Markdown characters
- 100% 客户端 – All parsing and conversion happens in your browser
常问问题
-
What is the Markdown table syntax?
Markdown tables use pipe characters (|) to separate columns and hyphens (-) for the header separator row. Each row is a single line with pipes between cells. The second row defines column alignment: left-aligned (:---), centered (:---:), or right-aligned (---:). Not all Markdown renderers support tables, but GitHub, GitLab, and most modern platforms do.
-
How does RFC 4180 CSV parsing handle commas inside fields?
RFC 4180 specifies that fields containing commas, newlines, or double quotes must be enclosed in double quotes. A double quote within a quoted field is escaped by preceding it with another double quote. For example, a cell containing 'Hello, World' would be encoded as one quoted field rather than two separate columns.
-
Why do Markdown tables need a header separator row?
The separator row (the line with hyphens and colons) is required by the Markdown table specification to distinguish the header from body rows. Without it, most Markdown parsers will not recognize the content as a table. The separator row also defines column alignment using colon placement.
-
Can Markdown tables handle merged cells or colspan?
No. Standard Markdown table syntax does not support merged cells, colspan, rowspan, or nested tables. Each cell occupies exactly one column and one row. For complex table layouts requiring merged cells, you need to use raw HTML within your Markdown document instead.
