Questions tagged [csv]

A comma-separated values (CSV) file is "a delimited text file that uses a comma to separate values" according to Wikipedia. It stores tabular data (numbers and text) in plain text. Blender itself does not have importers or exporters for CSV files, but the format is used by any number of add-ons for importing and exporting data to other programs. Use this tag for Blender-specific questions about the use of CSV Files.
