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) For ReadCSV this gives the delimiter for CSV entries, with a default of ",". For ReadJSON
        this is the character set for converting Unicode escape sequences in strings, with a default
        of "UTF8". See the ExifTool Charset option for a list of valid character sets.

    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.
