# Parsing non-standard CSV with different Java CSV libraries
Unfortunately, there is no real industry standard for CSV files.
The closest thing we do currently have (since 2005) is [RFC 4180](https://tools.ietf.org/html/rfc4180).
Working with non-standardized data often comes with surprises, but what exactly happens when parsing
CSV data that doesn't match this RFC?
This project is about to find that out...
This benchmark project was created for the development of
[FastCSV](https://github.com/osiegmar/FastCSV).
> [!NOTE]
> Since this comparison uses the result of FastCSV as a reference value (expected result), the comparison is highly
> biased.
## Implementations under test
- Commons CSV 1.12.0
- CSVeed 0.8.2
- FastCSV 3.3.1
- Jackson CSV 2.18.0
- Java CSV 2.0
- Opencsv 5.9
- picocsv 2.4.0
- sesseltjonna-csv 1.0.25
- SimpleFlatMapper 9.0.2
- Super CSV 2.4.0
- Univocity 2.9.1
## Execute
./gradlew run
# Results
To have results which are unambiguous to compare (even with multi-line records), we need to use
some special characters.
The libraries itself don't get in touch with these special characters as the conversion is done
from the outside.
| Character | Usage |
| --------- | ----------------- |
| `␣` | Space |
| `␍` | Carriage return |
| `␊` | Line feed |
| `[SE]` | Skip emtpy rows |
| `⏎` | New row |
| `↷` | New column |
| `◯` | Empty field |
| `∅` | Empty list |
