Convert CSV to HTML
Updated Jul 2026
CSV is plain rows of comma-separated data, the kind spreadsheets export. HTML is the markup that web browsers render as pages. Converting CSV to HTML turns each row of data into a table a browser can display, with every column and value kept intact. It can be done entirely on your own computer, without uploading the file anywhere.

How to convert CSV to HTML
- Open Morphjet and drag in the CSV file, or a whole folder of them, that you want to convert.
- Choose HTML as the output format.
- Convert. Morphjet writes an HTML table with your data next to the original file, and nothing leaves your machine.
CSV vs HTML: what actually changes
| CSV | HTML | |
|---|---|---|
| Opens where | Any spreadsheet app or text editor | Any web browser |
| File size | Smaller, just the raw data | Larger, the same data wrapped in markup |
| Data preserved | Every row and column, as-is | Every row and column, as a table |
| Editable as data | Easy, in any spreadsheet or text editor | Harder, since the data sits inside tags |
| Formatting and styling | None, plain data only | Supports fonts, colors, links, and layout |
When to convert, and when not to
Convert CSV to HTML when you want to publish the data on a web page, drop a table into a report or email, or share something anyone can view in a browser without opening a spreadsheet app.
Keep the CSV if you still need to sort, filter, or run formulas on the data, since a spreadsheet app does that far better than a static HTML table.
Why not just use an online converter?
CSV exports often hold real records, customer lists, financial figures, survey answers, pulled straight out of a spreadsheet. Running that file through an online CSV to HTML converter means sending that data to a server you don't control, and you don't know what happens to it after. Converting on your own computer keeps the data exactly where it started, on your machine.
Questions
Does converting CSV to HTML lose any data?
No. HTML can represent every row and column from the CSV exactly, so the conversion itself is lossless. What you don't get for free is formatting beyond a basic table, since CSV never had any.
Will the HTML table keep things like currency symbols or date formatting?
Not automatically. CSV stores everything as plain text, so numbers and dates come through exactly as the CSV wrote them. Any special formatting from the original spreadsheet has to be added back in afterward.
Can I just open the HTML file after converting?
Yes. Double-click it and it opens in any web browser as a plain table, no web server or hosting needed.
Can I convert CSV to HTML without uploading the file anywhere?
Yes. Morphjet converts it on your own computer, so the data never leaves your machine or touches an outside server.
Can I still edit the data once it's an HTML table?
You can edit it by hand in a text editor, but you lose the sorting, filtering, and formulas that a spreadsheet app gives you with the original CSV.
