ECSV

ECSV, or Extended CSV, is a file format designed to extend the capabilities of the traditional Comma-Separated Values (CSV) format. While CSV is widely used for storing tabular data, it has limitations in terms of data types, metadata, and hierarchical structures. ECSV addresses these limitations by introducing additional features.

One of the key features of ECSV is its support for multiple data types beyond simple strings. This includes integers, floats, booleans, dates, and even complex data structures like lists and dictionaries. This allows for more precise and accurate data representation.

ECSV also includes support for metadata, which can be used to describe the data in the file. This metadata can include information about the data types, units of measurement, and other relevant details. This makes ECSV files more self-descriptive and easier to understand and use.

Another important feature of ECSV is its ability to handle hierarchical data structures. While CSV is inherently flat, ECSV can represent nested data, making it suitable for more complex data models. This is achieved through the use of special characters or conventions to denote nested levels.

ECSV files are typically saved with the .ecsv extension and can be read and written using various software tools and libraries. The format is designed to be simple and easy to use, while still providing the flexibility needed for modern data applications.
