Patron data imported into Theatre Manager must be in either the industry standard Tab Delimited or Comma Delimited format. This format is supported by most applications. If it is not, a tool like Microsoft Excel or Word is very useful for helping massage data before importing into Theatre Manager.
Tab delimited format means that each field in the database is separated by a tab and the last field in each record has a carriage return after it. The first record in the data may be the title of the fields for clarity, although this is not necessary.
