How to use the Markdown table generator

  1. Copy cells from Excel or Google Sheets (or CSV text) and paste them into the box.
  2. Choose Markdown, HTML or plain-text ASCII and the column alignment.
  3. Copy the neatly aligned table into GitHub, Notion, a README, a forum or an e-mail.

Writing Markdown tables by hand means counting pipes and dashes; this does it instantly and keeps columns aligned so the source is readable too. Tabs from spreadsheets, commas, semicolons and quoted CSV cells are all detected automatically, and pipe characters inside cells are escaped.
