Output is fixed-width — each column is padded to its widest value automatically.
Convert CSV into fixed-width text
Fixed-width (fixed-length) text aligns every column by character position instead of using a separator — still required by many mainframe, banking and reporting systems. To convert CSV to fixed width text file, this tool measures each column and pads the values so they line up.
Paste or upload your CSV and the converter computes each column’s width from its longest value, then writes aligned rows. The result looks like a clean table in any monospaced editor and is ready for systems that parse by position.
Going the other way — reading fixed-width text into CSV — is handled by fixed width to CSV. For other separators, see CSV to delimited text.
How to use it
붙여넣기 또는 업로드
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.

Automatic column widths
The converter scans every row to find the longest value in each column, then pads all values in that column to match, adding a space of separation. The output aligns cleanly without you measuring anything.
Reading it back
Because the widths are consistent, systems that parse by position can read the file reliably. If you later need it as CSV again, the fixed width to CSV tool can auto-detect the same boundaries.
Monospaced viewing
View the result in a monospaced font (most code editors) to see the columns line up. Proportional fonts will not show the alignment correctly even though the file is valid.
Encoding
Output is UTF-8. Note that multi-byte characters occupy one character position here, which is the usual convention for text alignment.
Fixed-width text, then and now
Fixed-width formats predate delimited files and still anchor a surprising amount of infrastructure in banking, government and insurance. Their appeal is determinism: because every field occupies a known range of character positions, a reader never has to guess where one column ends and the next begins, and there is no delimiter to collide with the data. Converting a CSV to fixed-width text lets modern, comma-based data flow into those systems unchanged. The key is consistency, which this tool guarantees by padding each column to the width of its longest value. When a downstream specification dictates exact widths, keep that in mind — you may need to pad the source so columns match the required layout. View the output in a monospaced font to confirm the alignment, and remember the fixed-width-to-CSV tool reverses the process whenever you need the data back as CSV.
CSV to Fixed Width Text Converter — FAQ
How are column widths chosen?
Each column is padded to the width of its longest value, with a space of separation.
What is fixed-width text used for?
Mainframe feeds, banking files and legacy reports that parse data by character position.
Why doesn’t it line up in my viewer?
Use a monospaced font; proportional fonts will not show the alignment.
Can I convert it back to CSV?
Yes, use the fixed width to CSV tool.
