CSV to HTML Table Converter

How to use

1. 1Paste your CSV, TSV, or pipe-separated text into the input. Copying directly from Excel, Google Sheets, Numbers, or Airtable usually pastes as TSV, which the auto-detector handles.
2. 2Leave Delimiter on Auto and check the detected label below the picker, or pick Comma, Tab, Semicolon, or Pipe explicitly if your data is unusual.
3. 3Pick a style mode: Plain HTML for pages with their own table CSS, Inline styles for HTML emails and CMS rich-text fields, or CSS classes for a scoped stylesheet you can tweak later.
4. 4Toggle First row is the header on or off, then enable Border, Striped rows, Compact padding, Cell line breaks, or Indent output to taste, and optionally add a caption.
5. 5Click Copy HTML to copy the markup, or read the live preview below to verify the table before you paste.

About this tool

CSV to HTML Table Converter turns a block of comma-separated, tab-separated, semicolon-separated, or pipe-separated values into a semantic HTML table that drops cleanly into a documentation page, a blog post, a static site, an HTML email, a CMS rich-text field, a Notion or Confluence page, or any other place that accepts HTML. Delimiters are auto-detected by scoring each candidate (comma, tab, semicolon, pipe) on column-count consistency across the first 30 non-empty lines, and the detected delimiter is shown above the controls so you can verify it. You can also pin a specific delimiter when the auto-detector picks the wrong one. The CSV scanner is RFC-4180-style: quoted fields are respected, doubled quotes inside quoted fields decode to a single quote, embedded newlines inside quoted fields are preserved through to the rendered table (optionally as a real <br> tag), and both LF and CRLF row terminators work. A first-row-as-header toggle controls whether the parsed top row becomes the <thead> or whether the tool synthesizes Column 1, Column 2, etc. so the output is always semantically valid. Three styling modes cover the common copy-paste targets: Plain HTML emits a clean <table> with no inline styles or classes for pages that already have their own table CSS, Inline styles puts a style attribute on every element so the table survives email clients and CMS sanitizers that strip <style> blocks (the format Mailchimp, HubSpot, and most marketing platforms expect), and CSS classes emits semantic class names like zst-table, zst-table-bordered, and zst-table-striped along with a scoped <style> block so the copied snippet renders correctly without any external CSS. Optional caption, border, striped rows, compact padding, and indented output are independent toggles, and cell content is HTML-entity-escaped so user data containing ampersands or angle brackets renders as literal text instead of becoming markup. A live preview below shows exactly how the chosen markup will render in a browser, and the meta strip reports row and column counts, character length, and byte size so you can verify the output at a glance. Useful for turning Excel, Google Sheets, Numbers, or Airtable exports into a documentation table, prepping HTML email tables for newsletters and transactional templates, embedding tabular data in a static site, building changelog or feature-comparison tables, or converting any spreadsheet you can copy as TSV into a copy-paste-ready HTML snippet. Everything runs locally on your device, so the rows you paste here, including any internal data, never leave your browser.
