Frequently Asked Questions
What is the difference between CSV and TSV?
∨
CSV (Comma-Separated Values) uses commas as delimiters. TSV (Tab-Separated Values) uses tabs. TSV is better for data containing commas, while CSV is more universally supported. This tool handles both formats.
How do I convert CSV to a Markdown table for GitHub?
∨
Paste your CSV data, ensure 'First row is header' is checked, and copy the Markdown output. GitHub automatically renders Markdown tables in READMEs, issues, and comments.
Can I use custom delimiters?
∨
Yes. Select the delimiter from the dropdown: comma, tab, semicolon, or pipe. The auto-detect feature will try to identify the most likely delimiter from your input.
How do I align columns in the Markdown table?
∨
After pasting data with headers enabled, click the column alignment buttons (left/center/right) above the output. Colons in the separator row control alignment: :--- for left, :---: for center, ---: for right.
Does this tool handle quoted fields?
∨
Yes. Fields enclosed in double quotes are parsed correctly, including fields that contain commas, newlines, or escaped quotes (doubled quotes like "").
Can I paste data from Excel or Google Sheets?
∨
Yes. Copy cells from Excel or Google Sheets and paste directly into the input area. The tool will auto-detect the tab delimiter. Make sure to select 'First row is header' if applicable.
What Markdown table format does this tool generate?
∨
The tool generates GitHub-Flavored Markdown (GFM) table syntax, which is the standard format supported by GitHub, GitLab, Bitbucket, and most Markdown renderers.
Is my data private?
∨
Yes. All parsing and conversion happens entirely in your browser. No data is uploaded to any server. You can even disconnect your internet and the tool still works.
Can I convert Markdown tables back to CSV?
∨
This tool focuses on CSV-to-Markdown conversion. For Markdown-to-CSV, you can use our other tools or simply copy the table from Markdown and paste into a spreadsheet.
What if my CSV has inconsistent column counts?
∨
The tool pads shorter rows with empty cells to match the maximum column count. This ensures the Markdown table has consistent columns throughout.
