Reading CSV as raw text is painful, and you want to actually see the rows and columns laid out like a spreadsheet.
This viewer detects the delimiter, parses the fields, and renders a real HTML table, with a header row option and a live count of rows and columns.
How to use CSV Viewer Online
- Paste your CSV into the left panel.
- Use the header toggle to treat the first row as column headers.
- Read the table preview, and copy the normalized CSV if you need it.
What you can do with it
- Preview a CSV before importing it.
- Check how many columns a file really has.
- Inspect headers and the first rows of an export.
Good to know
A real viewer parses the cells and shows a table rather than fixed-width text, so quoted commas appear inside a single cell. The preview shows the first few hundred rows for speed while reporting the full counts.
Frequently asked questions
Does it show a real table?
Yes. The CSV is parsed and rendered as an HTML table, not as monospaced text, so columns are clear.
How is the delimiter detected?
The first non-empty line is inspected to choose the most likely delimiter among comma, semicolon, tab and pipe.
Is my data private?
Yes. Parsing and rendering happen entirely in your browser, with nothing uploaded.
