Usage Examples
Retrieve PDF metadata
/**
* Retrieves metadata of a Drive PDF file and logs the result.
*/
function getPdfMetadata() {
const pdfFileId = '___PDF_FILE_ID___'; // Drive file ID of the target PDF
// Fetch the PDF as a blob from Drive
const pdfBlob = DriveApp.getFileById(pdfFileId).getBlob();
// Call PDFApp and output the metadata
PDFApp.setPDFBlob(pdfBlob)
.getMetadata()
.then(meta => {
Logger.log(JSON.stringify(meta, null, 2));
})
.catch(err => Logger.log(err));
}Replace ___PDF_FILE_ID___ with an actual Drive file ID and run the function; title, author, page info and other metadata will be printed in the execution log.
