What is a CSV file?
CSV stands for 'Comma Separated Value(s)' and is a format to store structured data using text files. In a CSV file, each line is a data record. And each record is made of fields separated by commas (or sometimes by semicolons ';' or tabular keys).
CSV files are a common way to transfer data between applications. Because it relies on text files, the CSV format is a simple way to export database or spreadsheet data.

- Converting data types is a common task for CSV cleaning. It ensures data accuracy and consistency by transforming data values into standardized formats.

Data type conversion is important for filtering your CSV and transforming your string data into standardized formats to be imported into other tools.

- Split and Merge CSV columns
- Splitting and merging CSV columns is a useful technique for CSV cleaning. It helps you to restructure and organize your data in a more meaningful way.

- Reconcile your data from multiple CSV files
- Data reconciliation is easy with Datablist. Import your multiple data sources into several collections. Then select common identifiers between the lists to join them together.
