Where 5 KB matters
A 5,120-byte file: larger than a cookie, smaller than a typical HTTP header limit. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Browser cookies | 4,096 bytes per cookie | 5 KB does not fit in one cookie. |
| Vite asset inlining | 4 KB by default (assetsInlineLimit) | A 5 KB asset is emitted as a separate file rather than inlined as base64. |
| nginx and Apache request headers | 8 KB per header line by default | 5 KB fits; the 10 KB sample does not. |
Use this file for
- Checking asset-inlining thresholds in bundlers
- Checking delimiter and encoding detection
- Load-testing with many rows
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.
