CSV2HPP Converter

This command-line utility converts the content of a .CSV file (comma-separated values) into a header file for C/C++ software projects. Afterward, #include the resulting header file and immediately start to develop on a structured, well-formed dataset (and skip error-prone steps like file delivering, loading, parsing, converting, and checking).

▶️ Usage

1. Export or download your database in CSV format, e.g. to: bucket_list.csv
2. Open the CSV file in a text editor and add datatype hints to the header line, e.g.: Location (std::string), Latitude (double), Longitude (double)
3. Execute in a terminal window: csv2hpp bucket_list.csv POI > bucket_list.hpp.
4. Copy the generated header file into your project and include it (#include “bucket_list.hpp”).

💡 Hints

• Build csv2hpp by executing: cd src && cmake . && make (just requires cmake and a C++ compiler)
• Datatype hints are mapped to C/C++ datatypes as follows: (std::string) → std::string, (double) → double, (skip) skips the entire column. Supported are 95 datatype hints as defined in: datatype_hints.csv
• Empty CSV data cells are mapped to “” for strings and to 00 for everything else (as a hint).
• Precision hints such as ‘±05’ are removed in float or double values (not supported in C/C++).
• Supports also big .CSV files: omits whitespaces, removes trailing ‘0’. It’s recommended to use ‘const char*’ instead of ‘std::string’ which can break some compilers.
• More conversion examples can be found in the 📁examples subfolder.
