CSV Pretty Printer
Align CSV data into a padded, readable monospace table for quick eyeballing.
Pads every column in a CSV file out to its widest value so rows visually line up like a table — useful for quickly reading a CSV export in a plain-text context (a terminal, a chat message, a code comment) where a real spreadsheet view isn't available. The padded output is for reading, not for reuse — pipe it through CSV Formatter first if you need valid CSV back out.
Example: A 3-column CSV with a short header row and longer data rows pads every column out to its widest value, so "name", "age", and every row beneath them line up in neat columns, readable at a glance in a monospace font.
How it works
- Paste CSV data
- Every column is padded to its widest value, instantly on your device
- Read the aligned result like a plain-text table
Frequently asked questions
Is the padded, aligned output still valid CSV I can reuse?
No — the extra padding spaces become part of each cell's value, which breaks a real CSV import. This is for reading only; use CSV Formatter if you need clean, reusable CSV.
Is my data uploaded anywhere?
No — CSV Pretty Printer runs entirely in your browser using JavaScript/WebAssembly. Your data is never sent to a server.
Does this work with tab-separated (TSV) data too, not just comma-separated?
This specifically parses comma-separated CSV. For tab-separated data, convert it with TSV Converter first, or use a comma-delimited copy.
