Where 50 KB matters
A 51,200-byte file, half of the default body limit in several web frameworks. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB by default | 50 KB is accepted; 500 KB is rejected with 413 unless the limit is raised. |
| Base64 encoding | Adds 33 percent | 50 KB becomes about 67 KB when embedded in JSON. |
Use this file for
- Testing document previews
- Testing data import features
- Checking delimiter and encoding detection
Testing notes for CSV
- Excel opens CSV files using the system locale, so a file that works in one country shows everything in one column in another.
- Values beginning with =, +, - or @ can be executed as formulas when a CSV is opened in a spreadsheet, a risk known as CSV injection.
