Google quietly updated their Google Search Central documentation to note that they are now indexing .csv files. Comma-Separated Values (CSV)Comma-separated values (CSV) files are text files that save data in a tabular format that can be displayed as a spreadsheet. CSV files contain data in plain text, which means that the CSV files do not contain style elements like fonts nor does it contain images or active links.
