A header only CSV parser which is fast and versatile with modern C++ API. Requires compiler with C++17 support. [Can also be used to efficiently convert strings to specific types.](#the-converter)

# Single header

The library can be used with a single header file **`ssp.hpp`**, but it suffers a significant performance loss when converting floating point values since the **`fast_float`** library is not present within the file.

## Headers
|

|

The parser can be told to use only certain columns by parsing the header. This can be done with the **`use_fields`** method. It accepts any number of string-like arguments or even an **`std::vector<std::string>`** with the field names. If any of the fields are not found within the header or if any fields are defined multiple times it will result in an error.

The header is parsed with the same rules as other rows, the only difference is that **`multiline`** will be disabled when parsing the header. To get the data that is
|
||||
present in the header as a **`std::vector<std::string>`**, the **`header`** method can be used, and to get the header line before it has been parsed, the **`raw_header`** method can be used:
|
||||
```cpp
|
||||
// ...
|
||||
ss::parser<ss::throw_on_error> p{"students_with_header.csv"};
|
||||
|

std::cout << p.raw_header() << std::endl;

std::cout << "> " << field << std::endl;

```shell

$ ./a.out

Id,Age,Grade

||||
> Id

||||
> Age

> Grade

Methods related to headers can also fail, the error handling of these is done in the same way as for other methods.
