What is an ECSV file?
More Information
Astronomer Tom Aldcroft developed the ECSV format to overcome limitations in the CSV format. For example, CSV datasets cannot contain metadata besides column names. ECSV files, on the other hand, can include metadata such as:
- Numerical data type
- Units
- Text descriptions of column content
ECSV files store this metadata in YAML-formatted data structures, located at the beginning of the file. Each line in the YAML data structure's datatype section contains metadata for a corresponding CSV data column.
How to open an ECSV file
You can open an ECSV file with Microsoft Visual Studio Code (multiplatform), GitHub Atom (multiplatform), or any other text or source code editor to view the data it contains.
Many ECSV files are meant to be used with astropy, a Python library used by astronomers and astrophysicists.
