GroupDocs.Metadata for .NET makes it easy for .NET developers to edit metadata information to XLSB files from within their applications by implementing a few easy steps.
// Edit XLSB creation date
using (var metadata = new GroupDocs.Metadata.Metadata("input.xlsb"))
{
// set the value of each property that satisfies the predicate::
// property contains the date/time the document was created
// update the file creation date/time if the existing value is older than 3 days
var affected = metadata.UpdateProperties(
p => p.Tags.Contains(GroupDocs.Metadata.Tagging.Tags.Time.Created) &&
p.Value.Type == GroupDocs.Metadata.Common.MetadataPropertyType.DateTime &&
p.Value.ToStruct() < DateTime.Today.AddDays(-3), new GroupDocs.Metadata.Common.PropertyValue(DateTime.Today));
Console.WriteLine("Properties set: {0}", affected);
// Save result XLSB
metadata.Save("output.xlsb");
}
The GroupDocs.Metadata API lets developers easily edit document details (metadata) in various formats using their .NET applications. Programmatically add, update, search for, and remove document properties.
GroupDocs.Metadata simplifies adding different properties to documents and files within your .NET apps. Developers can easily apply, update, or remove document properties programmatically.
The API offers extensive options for managing document properties. Developers can efficiently find and process any hidden data placed in business files.
Depending on the document format, developers can utilize existing properties like EXIF data for images. This might include information like camera details, resolution, creation date, and more.
// Load file using the Metadata class
using (Metadata metadata = new Metadata("input.mp3"))
{
var root = metadata.GetRootPackage<MP3RootPackage>();
if (root.Lyrics3V2 == null)
{
root.Lyrics3V2 = new LyricsTag();
}
// Update lyrics data
root.Lyrics3V2.Lyrics = "[00:01]Test lyrics";
root.Lyrics3V2.Artist = "test artist";
root.Lyrics3V2.Album = "test album";
root.Lyrics3V2.Track = "test track";
// {emore_features.code_1.comment_3}
root.Lyrics3V2.Set(new LyricsField("ABC", "custom value"));
// Save updated file
metadata.Save("output.mp3");
}
