Google can now index CSV files on search engine results.

 As of my last update in October 2021, Google can index and display CSV (Comma-Separated Values) files in search results. This means that if you have a CSV file on your website that contains relevant and useful information, Google may show it as a search result when users search for related queries.

When Google indexes a CSV file, it looks for structured data within the file, such as headers and columns. It then uses this information to understand the content and potentially display it in search results. This can be particularly helpful for data-driven content, such as lists, tables, or datasets.

However, it's important to note that Google's ability to index and display CSV files in search results may vary, and it depends on various factors such as the relevance of the content, the quality of the file, and Google's algorithms. Additionally, Google may prioritize other types of content, such as webpages or documents, over CSV files in search results.

To optimize your CSV files for search, consider the following best practices:

1. Ensure the CSV file is accessible and crawlable by search engines by hosting it on a publicly accessible web server.

2. Include relevant and descriptive headers in your CSV file to provide context to search engines.

3. Use meaningful and descriptive filenames for your CSV files.

4. Consider providing additional context or explanations in a separate webpage or document that accompanies the CSV file.

As with any content you want to appear in search results, it's essential to follow general SEO best practices, such as using relevant keywords, providing high-quality content, and ensuring your website is optimized for search engines.

Keep in mind that Google's indexing capabilities and algorithms are subject to change, so it's always a good idea to stay updated with the latest announcements and guidelines from Google.
