About CSV files
CSV test files from 10 KB to 10 MB are available free. They contain synthetic Japanese names, addresses and phone numbers, so import processing can be verified against data shaped like real business records.
CSV has no magic bytes of its own, so its format cannot be confirmed from the content. Validation therefore centres on encoding, delimiters, and quoting. Encoding-specific files live on the encoding test page.
Typical uses
- Exercising a CSV import feature at high row counts
- Measuring bulk-insert performance into a database
- Confirming rows are streamed rather than all held in memory
- Checking whether the file opens in Excel
