Convert a CSV file to a text file online
When you specifically need to convert a CSV file to a text file online, this tool focuses on the file workflow: drop in a .csv, choose how the text should look, and download a .txt. It runs in the browser, so the file stays on your device.
Pick the separator that suits the destination — tab for safe, readable columns, comma to keep CSV-style text, pipe for system feeds, or space for a light layout — and set the encoding and line endings before downloading.
Prefer to paste rather than upload? Use CSV からテキストへ. Want the reverse, text into a CSV file? See text to CSV file online.
How to use it
貼り付けまたはアップロード
Add your text or drop a file — it is read locally in your browser, never uploaded.
Preview & adjust
Check the live table and the row / column counts, then tweak the delimiter or options if a column looks off.
Copy or download
Grab the result with Copy or Download. You can reopen recent conversions from this device too.

.txtを生成する際に重要なオプション。
Choosing the separator
Tab-separated keeps columns intact and readable; comma reproduces CSV-style text in a .txt; pipe suits older import tools; space gives a minimal look. Quoting still protects values that contain the chosen separator.
Encoding for the destination
Leave encoding as UTF-8 for editors and scripts. If the text file will be opened in Excel and contains accents or CJK characters, enable the UTF-8 BOM so they display correctly.
Windows vs Unix line endings
Choose CRLF for Windows Notepad and Windows systems, or LF for macOS, Linux and most code tools, so line breaks render properly.
プライバシー
The CSV is read and converted locally; it is never uploaded, which makes the tool safe for confidential exports.
Choosing the right text file for the job
A text file is only useful if the system on the other end can read it, so the most important decision is the separator. Tab-separated output is the safest default because it survives values that contain commas and pastes neatly into spreadsheets; comma keeps a familiar CSV feel inside a .txt; pipe suits database loads and older feeds; and space gives the lightest, most human look. Beyond the delimiter, two settings prevent the usual headaches: line endings should match the destination — CRLF for Windows tools, LF for macOS, Linux and code editors — and the UTF-8 BOM should be enabled only when Excel will open a file containing accented or non-Latin characters. With those chosen, the download is a clean, predictable text file that other tools can parse without surprises.
