About Data to HTML
This tool renders a CSV, TSV or JSON file as a standalone HTML page with a bordered, readable table. The page has its own basic styling, so you can open it in any browser, email it or drop it into a website without extra CSS. Unlike the CSV exports, the table columns include every key found in any JSON record, not just the first.
When it helps
- Sharing a small dataset with someone who doesn't have spreadsheet software.
- Pasting a formatted table into a blog post, intranet page or documentation site.
- Viewing a JSON export as a grid to spot missing or odd values quickly.
- Attaching a printable version of a report table to an email.
Tips
- Values are HTML-escaped, so any markup in your data is shown as text instead of being run.
- For JSON, records missing a field get an empty cell in that column. Nested objects are not expanded and show up as "[object Object]".
- CSV input needs a header row and the same number of fields on every row, otherwise the conversion stops with a parse error.
- Very large files make a large HTML page that browsers render slowly. Filter or split the data first if it has many thousands of rows.
Good to know
Quick answers about data to html in your browser.
No. The output is a static table with no scripts. If you need sorting, sort the data first with the CSV sort tool, then convert it.
Open the downloaded file in a text editor and copy the table element, plus the short style block if you want the same borders and spacing, into your page.
Yes. There is no sign-up, no watermark and no limit on how many files you process.
No. Files are read and processed locally in your browser, so they never leave your device.
