The CSV data source must contain at least 3 records or line items, and each record may contain up to a maximum of 3070 characters. This limit applies with two fields marked as searchable and for each additional searchable field this limit reduces by 1. For example, with 10 searchable fields the limit would reduce to 3062. Values within each record must be semicolon separated and each record must contain the same number of records. Optionally, the CSV file may contain a header row, which also must contain the same number of values.
The CSV data source must include at least one ID column for which each record has a unique value. The values in this column can be either purely numeric or alphanumeric.
The maximum file size for a CSV file is 150 MB.
