Convert TXT to CSV
Updated Jul 2026
TXT is a plain text file with no built-in structure, just lines of text. To convert TXT to CSV, a converter looks for a consistent separator, like a comma or tab, already used in the file and splits each line into columns along it. Doing this on your own computer means the data never has to leave your machine.

How to convert TXT to CSV
- Open Morphjet and drag in the TXT file you want to convert, or a whole folder of them at once.
- Choose CSV as the output format.
- Convert. Each line becomes a row, split into columns wherever the text already uses a comma, tab, or other consistent separator.
- The CSV is written locally next to your original file, and nothing leaves your machine.
TXT vs CSV: what actually changes
| TXT | CSV | |
|---|---|---|
| Structure | Plain lines of text, no built-in columns | Rows and columns, separated by commas |
| Opens in | Any text editor | Spreadsheet apps and text editors |
| Sorting and filtering | No, you'd have to do it by eye | Yes, in any spreadsheet app |
| File size | About the same | About the same, plus a few bytes for commas |
| Quality | Lossless | Lossless, if the original text had a consistent separator to split on |
When to convert, and when not to
Convert TXT to CSV when you have a plain text file with data separated by commas, tabs, or another consistent character, such as an exported log or list, and you want to open and sort it as a spreadsheet.
Keep the TXT file if it's just prose or notes with no consistent line-by-line structure, since a CSV can't add columns that weren't already implied in the text.
Why not just use an online converter?
A TXT export of contacts, transactions, or query results can hold information you'd rather not hand to a stranger's server. Many online converters require uploading the file to a website before they'll rebuild it as a spreadsheet. Converting on your own computer keeps that data on the machine you already trust.
Questions
Does converting TXT to CSV lose any data?
No, if the text already has a consistent separator like a comma or tab, splitting it into columns is lossless. If the text has no clear structure, the converter can only put each full line into a single column, since it can't invent structure that isn't there.
How does Morphjet know where to split each line into columns?
It looks for a separator, comma, tab, or similar, that shows up consistently across the file's lines. If your text doesn't use one, each line just becomes a single-column row instead of separate columns.
What programs can open a CSV file?
Spreadsheet apps on Mac and Windows, most database and data analysis tools, and any plain text editor, since a CSV is still just text underneath.
Can I convert TXT to CSV without an internet connection?
Yes. The conversion happens locally, so you can turn off wifi entirely and it will still work.
