Is the first row used as the table header?

Yes. The first CSV row is always treated as the header row in the resulting Markdown table.

Can I choose column alignment?

Yes. You can set each column to left, center, or right alignment, which is encoded with colons in the separator row.

What separators are supported?

Commas, semicolons, tabs, and pipes are auto-detected. You can also override the delimiter manually if your data uses something else.

Is the CSV uploaded anywhere?

No. Parsing happens entirely in the browser — your data never leaves the page.

Quick Start

How to convert CSV to MD

Parses CSV per RFC 4180 (quoted fields, escaped quotes), then formats as a Markdown table.

01
Paste CSV
Comma-separated. Quoted fields with embedded commas work.
Parsing runs through marked with GFM extensions enabled — tables, task lists, strikethrough, and fenced code blocks all match GitHub’s rendering.

02
Header toggle
Use first row as header, or auto-generate Column 1/2/3...
Soft-break behaviour is configurable: by default a single newline becomes a space (CommonMark), toggle on for chat-style <br> insertion.

Pick alignment
All columns left, center, or right. Future: per-column.
The preview is scoped under a .mde class so its CSS doesn’t bleed into the rest of the page. Output HTML is whitespace-controlled for clean diffs.

Pro tips

Author Markdown that renders everywhere

GFM is the safe default

GitHub-Flavored Markdown is the de-facto baseline (tables, task lists, strikethrough). CommonMark is stricter but ubiquitous as a fallback.

Soft-break behaviour varies

A single newline is a space in CommonMark, a <br> in GFM. Toggle soft breaks when source matters.

Escape inside code fences

Backticks inside fenced blocks need a longer fence — three becomes four. Use ~~~ if your content has many backticks.

Anchors are slugified

GitHub lowercases, strips punctuation, and joins with hyphens. Duplicate headings get -1, -2 suffixes.

Tables need a header row

The dash row sets alignment (:---, :-:, ---:). Use Table Aligner for diff-friendly columns.

Front matter is YAML

Triple-dash blocks at the top of files are parsed by static-site generators. Use the Front-Matter Validator to catch syntax errors.

Use Cases

When to convert CSV

Reports, docs, sharing.

Sheet exports

Export Google Sheets / Excel as CSV → MD. Render path uses marked with GFM extensions enabled (tables, task lists, strikethrough, autolinks), so what you preview matches what GitHub publishes bit-for-bit. Soft-break behaviour is configurable for chat-style vs prose Markdown.

GFM-compliant

DB results

Quick MD report from a CSV dump. Pairs cleanly with the Markdown Cheatsheet for syntax you can't quite remember — callout blocks, footnotes, definition lists. Output stays diff-friendly so style-only changes don't drown out real edits in PRs.

GitHub-perfect

Issue templates

Paste data into GitHub issues as tables. Cross-platform safe: anchors, code fences, and tables behave identically on GitHub, GitLab, Bitbucket, and Gitea. Heading-anchor slugs follow GitHub's lowercase-and-hyphenate rules so deep links survive a docs migration.

diff-friendly

Slack standups

Render CSV stats in standup channels. No server roundtrip — perfect for proprietary content you can't paste into a public tool. The full marked + GFM bundle ships with the page, so it works offline once loaded.

render-stable

Research notes

Embed measurement tables in Markdown docs. Front matter (YAML / TOML / JSON) passes through unchanged so static-site pipelines (Jekyll, Hugo, Astro, Eleventy) read it correctly. Pair with the Front-Matter Validator to catch syntax errors before deploy.

cross-platform

README data

Add stats / benchmarks to your README. Output is reproducible: identical input always produces identical Markdown, so doc-generation scripts can rely on it for snapshot tests and embedded into release workflows.

FAQ

Frequently asked questions

TSV / semicolons?

Currently CSV only. Convert your delimiter first (most spreadsheets export CSV).

Quoted fields?

Yes — RFC 4180 compliant. Double-quote inside quoted field becomes a literal quote.

Pipes in data?

Auto-escaped to \| so the Markdown table doesn't break.

Per-column alignment?

Not yet — use Markdown Table Generator for per-column control.

Is anything sent to a server?

No. CSV is parsed in your browser.
