Drop your HTML file. We'll convert it to CSV right here in your browser, your file never leaves your device.

or drop your file here.
Accepts .html, .htm, .xhtml
How it works
Click the dropzone above or drag a HTML from your desktop. Files of any size, there's no upload, so there's no upload limit.
The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.
Get your CSV the moment the conversion finishes. Convert another, or close the tab.
Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.
Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.
No account required. No watermark on the output. No queue. Drop a file, get a converted file.
Why convert HTML → CSV
Pull a table out of a web page or HTML report into CSV for a spreadsheet, a script, a database import, or a data pipeline. CSV is the universal tabular exchange format.
A report page shows a table you need in your analysis. Save the HTML, convert to CSV here, and load it into pandas, Excel, or your database with the headers and rows intact and commas safely quoted.
No table found in the HTML.
The converter extracts the first <table> element. Pages that render grids with <div>/CSS have no table to read. If there is no real table, copy the data into a spreadsheet and export CSV from there.
A cell with commas split into extra columns when I opened it.
The output is RFC-4180 CSV, so cells containing commas are wrapped in quotes. If a tool mis-parses them, it is not reading quoted fields. Import via your spreadsheet's text-import wizard and set the delimiter to comma.
Formats involved
HTML is the markup language of the web, every browser displays HTML documents natively. Files contain text plus tags (<h1>, <p>, <a>, etc.) describing structure and links. Modern HTML5 also supports embedded media (audio/video) and complex semantic markup.
How to open
Every web browser. Any text editor for source. Modern editors (VS Code) syntax-highlight HTML.
CSV is plain text, one row per line, fields separated by commas. The simplest possible tabular data format, which is exactly why it remains the most portable: every spreadsheet, database, programming language, and analytics tool reads CSV. Tradeoffs: no formulas, no formatting, no multiple sheets, and various edge cases around quoting fields that contain commas or newlines.
How to open
Excel, Google Sheets, Apple Numbers, LibreOffice Calc, any text editor, every database import wizard, every programming language with one line of code.

FAQ
Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.
Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.
Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.
Web pages; structured document interchange; readable archives. Universal tabular data interchange. The most common reason to convert is compatibility, CSV works in places where HTML doesn't, or vice versa.
Every web browser. Any text editor for source. Modern editors (VS Code) syntax-highlight HTML.
Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.
Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
