CSV Escape Tool

Escape values so they are safe CSV fields: quotes are doubled and fields with commas or line breaks are quoted. Runs in your browser.

如何使用 CSV escape

  1. 01

    Paste your input into the left panel.

  2. 02

    Adjust the options to match your data.

  3. 03

    Copy the result from the right panel.

What it does

This tool escapes each line you paste into a valid CSV field: values containing the delimiter, a double quote or a line break are wrapped in quotes, and embedded quotes are doubled.

It is handy when you are building a CSV by hand or in code and need one value made safe.

Private and unlimited

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.

常見問題

What are the CSV escaping rules?

Following RFC 4180: a field is quoted when it contains the delimiter, a double quote or a newline, and any double quote inside the field is written twice. Plain values are left untouched.

Which delimiter should I use?

Comma is the standard. Pick semicolon in regions where the comma is the decimal separator (common in German and other European exports), tab for TSV files, or pipe when your values already contain commas.

Is there a row or file-size limit?

There is no fixed row cap or daily quota. Because everything runs locally the practical limit is your device's memory, which comfortably handles the tens of thousands of rows most exports contain.

Is my data uploaded anywhere?

No. The conversion runs entirely in your browser with client-side JavaScript, so nothing you paste or drop ever leaves your device. That makes it safe for spreadsheets that contain customer emails, financial figures or other sensitive data.
