One is Flatfile, an import and management service designed to make it easier to get data into a system from a variety of file formats, including CSV. It offers AI-boosted column matching, collaborative data onboarding and a customizable workflow, so it's a good option for companies trying to improve data quality and reduce the cost of manual data munging.
Another good option is ChatCSV, an information retrieval service that lets you ask natural language questions of CSV files and get charts as an answer. It's good for exploring sales trends, customer behavior and campaign data, and it's a pretty easy way to get a handle on what's in a CSV file.
AskCSV is another option. This browser-based tool lets you ask questions and get answers straight out of your CSV files without having to upload data to a server. It uses AI technology to generate charts and otherwise present the data graphically, and it's designed to protect your privacy and security since it doesn't send your data out of your computer.
