Set up a data validation script (or use a prebuilt one) that verifies the data is formatted correctly and matches the schema. 4. For example, if you only accept numbers between 0 and 100, you can configure the validation script to raise an error when the input value does not fall in that range. 5. Run the script over the full file or the relevant section and examine the results. If there are any errors, investigate the underlying cause, address it, and rerun the validation.
