CSV, or Comma-Separated Values, is a simple file format used to store tabular data in plain text. Each line in a CSV file corresponds to a row in the table, and each value within that line is separated by a comma, making it easy to import and export data between different programs.

Why Convert CSV to FITS file?

FITS (Flexible Image Transport System) is the standard data format used in astronomy and scientific research to store images, tables, and measurement data along with detailed metadata. Converting CSV to FITS is useful when you need to bring tabular data into astronomy software or a scientific workflow that specifically works with the FITS format.

This is a specialized, technical conversion aimed at scientific and research use rather than everyday needs. The result packages your CSV data into a FITS file that astronomy tools and data pipelines can read. For general data work, spreadsheets and CSV are far more common, so keep your CSV for regular use. Reach for FITS only when a scientific program or research workflow specifically requires it.
