Where 100 KB matters
A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Express body parsers | 100 KB (102,400 bytes) by default | A request body of exactly this size passes; anything larger returns 413 Payload Too Large. |
| Gmail message clipping | About 102 KB of HTML | Longer messages are truncated behind a "view entire message" link. |
| Amazon DynamoDB items | 400 KB per item | 100 KB fits; the 500 KB sample does not. |
Use this file for
- Checking email size handling
- Checking delimiter and encoding detection
- Load-testing with many rows
Testing notes for CSV
- Values beginning with =, +, - or @ can be executed as formulas when a CSV is opened in a spreadsheet, a risk known as CSV injection.
- Splitting each line on commas breaks on quoted fields. Test with the quoted-fields sample before trusting an importer.
