NAME

       Image::ExifTool::Import - Import CSV and JSON database files

SYNOPSIS

           use Image::ExifTool::Import qw(ReadCSV ReadJSON);

DESCRIPTION

       This module contains routines for importing tag information from CSV (Comma Separated Value) and JSON
       (JavaScript Object Notation) database files.

EXPORTS

       Exports nothing by default, but ReadCSV and ReadJSON may be exported.

METHODS

   ReadCSV / ReadJSON
       Read CSV or JSON file into a database hash.

       Inputs:
           0) CSV file name.

           1) Hash reference for database object.

           2) Optional string used to represent an undefined (missing) tag value.  (Used for deleting tags.)

           3)  [ReadJSON  only]  Optional  character  set  for  converting  Unicode escape sequences in strings.
           Defaults to "UTF8".  See the ExifTool Charset option for a list of valid settings.

       Return Value:
           These functions return an error string, or undef on success  and  populate  the  database  hash  with
           entries  from  the  CSV or JSON file.  Entries are keyed based on the SourceFile column of the CSV or
           JSON information, and are stored as hash lookups of tag name/value for each SourceFile.
