Convert TXT to XLSX
Updated Jul 2026
TXT is a plain text file with no rows or columns, and XLSX is the spreadsheet format used by Excel and similar apps. To convert TXT to XLSX, open the file in a converter and export it as a spreadsheet, where each line typically becomes a row. Doing this on your own computer means the file's contents never have to leave your machine.

TXT vs XLSX: what actually changes
| TXT | XLSX | |
|---|---|---|
| Structure | None, just a sequence of lines | Rows and columns you can sort, filter, and calculate on |
| File size | Very small, plain characters only | Larger, the spreadsheet format adds overhead |
| Opens in | Any text editor, on any device | Spreadsheet apps such as Excel, Numbers, or Google Sheets |
| Formulas and formatting | Not supported | Fully supported, colors, formulas, multiple sheets |
| Splitting into columns | N/A, one stream of text | Automatic if the text uses a consistent separator like tabs or commas, otherwise everything lands in one column |
When to convert, and when not to
Convert TXT to XLSX when you have exported data, a log, or a delimited list sitting in a plain text file and you want to sort it, filter it, or run calculations on it in a spreadsheet.
Keep the TXT file if it's just prose or notes with no real rows and columns of data, since a spreadsheet won't add anything and only makes the file heavier to open.
Why not just use an online converter?
Text files often hold things people would rather not send anywhere, exported customer lists, financial figures, passwords, notes from a meeting. An online converter has to receive that file on a server you don't control before it can hand back a spreadsheet. Converting on your own computer means that data stays put, and you could do it with your wifi off and nothing would change.
Questions
Does converting TXT to XLSX lose any data?
No. Every line of the original text is preserved. What you don't get automatically is structure, the converter has to decide how to split lines into columns, which it does using tabs or commas if they're present.
Will each line become its own row?
Yes, by default each line of the TXT file becomes one row in the spreadsheet. If the line contains a consistent separator like a tab or comma, that gets split into separate columns.
Can a TXT file with commas or tabs be split into proper columns?
Yes, as long as the separator is used consistently throughout the file. If it's not consistent, you'll end up with everything in one column and some manual cleanup.
Will the XLSX have formulas or formatting?
No, since the TXT file never had any. You'll get plain data in cells, which you can then format or build formulas on top of once it's in the spreadsheet.
Can I convert TXT to XLSX without uploading the file anywhere?
Yes. A desktop app like Morphjet reads and converts the file on your own computer, so it never has to travel over the internet.
