NAME

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

SYNOPSIS

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

           $err = ReadCSV($csvFile, \%database);

           $err = ReadJSON($jsonfile, \%database);

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 or file reference.

           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.
