Drop a .txt file above or paste its contents — output is set to CSV by default.
Turn a text file into a CSV file
If you have a .txt file — a Notepad export, a log, an exported list or a copied table — this tool converts it to CSV without installing anything. It is the quickest way to convert a text file to CSV, whether the rows are separated by commas, tabs, spaces or pipes.
Upload the file (or drag it onto the box), and the converter reads it locally in your browser. It guesses the delimiter, splits the text into columns, and shows a live preview so you can confirm the result before downloading. Because nothing is uploaded to a server, it is safe for private or work data.
Need the reverse direction? Use CSV → 텍스트. Working with many files at once? The batch TXT to CSV converter handles up to 50 in one go.
How to convert a TXT file to CSV
Upload your .txt
Click browse or drag the text file onto the input box. You can also paste the contents directly.
Confirm the columns
The tool auto-detects the separator and shows a table. If columns look wrong, set 입력 형식 to Delimited and pick the delimiter, or use Fixed width.
CSV 다운로드
Keep the output on CSV (tick UTF-8 BOM for Excel) and click Download. Your file is ready.
Input and output example
A tab-separated text file becomes comma-separated CSV, ready for Excel.

몇 가지 설정으로 텍스트-CSV 변환을 보통 망치는 경우를 처리합니다.
When the .txt has commas inside fields
If a value already contains a comma (for example Doe, John), a naive split would break the row. This converter follows standard CSV rules: any field containing a comma, quote or line break is wrapped in double quotes on export, so the CSV stays valid and re-imports correctly.
When rows use tabs, spaces or pipes
Tab-separated and pipe-separated text are common in exports. Leave the input on 자동 감지 and the tool measures column consistency to pick the right separator. If your file is space-aligned into columns, switch 입력 형식 to 고정 너비 and the columns are detected by their positions.
Keeping a header row
If the first line of your text file lists column names, tick 첫 행은 헤더. The preview marks it as a header and, if you later export to JSON, those names become the object keys.
Encoding, leading zeros and Excel
To open the CSV in Excel with accents or CJK characters intact, enable UTF-8 BOM. To stop Excel turning IDs like 007 or long numbers into 7 or scientific notation, enable Excel 안전 숫자. For a deeper walkthrough see fix CSV Excel formatting issues.
Tips and edge cases
- There is no hard file-size limit, but large files use your device’s memory since everything runs locally — see large text file to CSV.
- To convert several text files together, use the batch converter and download them all at once.
- Prefer code? See Python, PowerShell or Linux guides.
