METHODS

24   ReadCSV / ReadJSON
25       Read CSV or JSON file into a database hash.
26
27       Inputs:
28           0) CSV file name.
29
30           1) Hash reference for database object.
31
32           2) Optional flag to set '-' values to undef in the database.  (Used
33           for deleting tags.)
34
35           3) [ReadJSON only] Optional character set for converting Unicode
36           escape sequences in strings.  Defaults to "UTF8".  See the ExifTool
37           Charset option for a list of valid settings.
38
39       Return Value:
40           These functions return an error string, or undef on success and
41           populate the database hash with entries from the CSV or JSON file.
42           Entries are keyed based on the SourceFile column of the CSV or JSON
43           information, and are stored as hash lookups of tag name/value for
44           each SourceFile.
