Yes, you can add regular expressions, set the column cells to be required or the column values to be unique, and create required dependencies between several columns. To implement that, you can use the validations array, which contains all verification rules. For more details and examples, you can check out our documentation. Note: We also offer cleaning functions for validating imported data against external data sources, modifying data and creating column cross dependencies. You can find more details below within the “Data Cleaning”-section.
