Convertisseur texte vers CSV en ligne

This online text to CSV converter is built for speed: paste your text and the result updates live, so there is no separate “convert” step to wait on. It is the web tool you reach for when you just need a quick, clean CSV.

Everything is browser-based. Drag a file in or paste from the clipboard; the tool detects the delimiter, shows a table preview with row and column counts, and lets you copy or download. Your data is processed locally and never uploaded.

Prefer to upload a TXT file specifically? Use online TXT to CSV. Need the file-download workflow front and center? See text to CSV file online.

Paste rows in the browser and get CSV instantly, no install required.

Live conversion as you type

The output regenerates a fraction of a second after each edit, so you can paste, tweak a delimiter, and see the effect immediately. There is no upload round trip slowing you down.

Drag-and-drop and paste

Drop a file from your desktop, or paste straight from a spreadsheet or web page. Spreadsheet copies are usually tab-separated, which Auto-detect recognizes while still exporting comma CSV.

Works on mobile too

The layout adapts to small screens, so you can convert a pasted list on a phone and copy the CSV into another app.

Private and offline-capable

Because it is pure browser JavaScript, the converter keeps working without a connection once loaded, and your text never leaves the device.

Running entirely in the browser changes the privacy calculation for everyday conversions. With a server-based tool, your pasted text or uploaded file travels across the network and sits, however briefly, on someone else’s machine. Here, the JavaScript that powers the converter does all the parsing on your device, so the data never leaves it — which matters when the rows are customer records, internal exports or anything you would not email to a stranger. A pleasant side effect is speed: there is no upload, no queue and no separate download step, so the CSV updates the instant you stop typing. It also means the tool keeps working offline once the page has loaded, useful on a flaky connection or a locked-down network. None of this costs you features: delimiter detection, the live table preview, multiple output formats and on-device history are all available without an account.
