NAME

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

CONTENTS

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.
