Convert text to a CSV file online
This tool is for when you want the file, online: paste or upload text and download a ready .csv without installing anything. It combines fast in-browser conversion with a clean file download in one place.
Paste a list or rows, or drag in a text file. The converter detects the delimiter, shows a live table so you can confirm the columns, and produces a standard CSV file that opens in Excel, Sheets and database tools. Nothing is uploaded.

在线将文本转为 CSV 文件的简单方法。
Paste or drag in your text
Use the clipboard for a quick list, or drop a text file to convert its contents. Both feed the same live preview, so you immediately see how the data will be structured.
Confirm the columns
Auto-detect chooses the separator and the table preview shows the result, including a warning if any row has a different number of columns. Adjust the delimiter or header before downloading.
Excel-safe options
Enable UTF-8 BOM for correct encoding in Excel, and Excel-safe numbers to keep leading zeros and long IDs intact in the saved file.
Download the file
Click Download to save a standard .csv. Because everything is local, the file is created on your device and can be shared like any other.
From clipboard to a shareable file
There is a meaningful difference between seeing a converted result on screen and holding a file you can save, attach and reuse. This page is built around that last step: it takes whatever text you paste or drop and produces a standard .csv that behaves like any other document. Because it opens in Excel, Google Sheets, Numbers and database import tools, a single conversion can feed a spreadsheet, a report and a data load without further fiddling. The settings that make the file dependable are the same ones worth checking every time — confirm the delimiter so columns split correctly, keep a header row if your first line names the fields, and switch on Excel-safe numbers when the data includes leading zeros or long identifiers. With those in place, you get a clean, portable CSV created entirely on your own device.
