How to export slides to HTML/PDF/DOC in google slides API - google-slides

Question

I'm using google slides API to create powerpoint presentation.
Where additional required functionalities are-
Export to PDF
Export to HTML
Export to Doc/Image format.
Is there a way given by Slides API?

Answer 1

The Slides API doesn't support exports directly, but that functionality is available from the Drive API:
https://developers.google.com/drive/v3/reference/files/export
Just use the Slides presentationId as the Drive fileId.

Assuming that you already have created the slide deck, the process to convert Google Slides to PDF would be as follows:
import apiclient.http as client_methods
# exporting the slide deck and specifying the desired final file type
data = drive_client.files().export(fileId=slide_id, mimeType='application/pdf').execute()
# request body to be send together the upload method
body = {'name':file_name, 'mimeType':'application/pdf'}
# wrapping the binary (data) file with BytesIO class
fh = client_methods.BytesIO(data)
# creating the Media Io upload class for the file (note that our original slide data is of binary type)
media_body = client_methods.MediaIoBaseUpload(fh,
mimetype='application/pdf')
# drive API v3 - .create | drive API v2 - .insert
pdf_file_id = drive_client.files().create(body=body, media_body=media_body).execute()['id']
# extra step: moving to desirable folder destination with the function method
def move_files(drive_client, id_, folder_id):
file_ = drive_client.files().get(fileId=id_, fields='parents').execute()
drive_client.files().update(fileId=id_, addParents=folder_id,
removeParents=file_['parents'][0],
fields='id,parents').execute()
# calling the move_files function.
# drive_client is authorized client, folder_id = desired destination directory (from url).
move_files(drive_client, pdf_file_id, folder_id)
Hope this helps.

As #Codik mentioned, Google Slides API doesn't support exports directly but you can use Google Drive API for exporting.
Here is my solution. I am replacing some text in the sides as well before exporting.
$substitutions = [
'text_block_1' => "My First Text",
'text_block_2' => "My Second Text"
];
// You can fond the google slide Id in the URL
$templateId = "Here comes the Google Slide Id";
$client = $certificationService->getGoogleClient();
$driveService = new \Google_Service_Drive($client);
$slidesService = new \Google_Service_Slides($client);
$copy = new \Google_Service_Drive_DriveFile(array(
'name' => 'Pdf Name' . ' presentation'
));
$driveResponse = $driveService->files->copy($templateId, $copy);
$fileId = $driveResponse->id;
// replaceable text should be covered with {{}}
// example = {{text_block_1}}
$requests = [];
foreach ($substitutions as $key => $value) {
$requests[] = new \Google_Service_Slides_Request(
[
'replaceAllText' => [
'containsText' => [
'text' => '{{'.$key.'}}',
'matchCase' => true
],
'replaceText' => $value
]
]
);
}
$batchUpdateRequest = new \Google_Service_Slides_BatchUpdatePresentationRequest(array(
'requests' => $requests
));
$updateResponse = $slidesService->presentations->batchUpdate($fileId, $batchUpdateRequest);
// here you can specify the file type you want to export as
$response = $driveService->files->export($fileId, 'application/pdf', array('alt' => 'media'));
$content = $response->getBody()->getContents();
// delete the exported file from the Google Drive
$driveService->files->delete($fileId);
Note:- In order for this code to work, the google slides should be shared with the Google Service Account email.
