In order to generate a .ppt/.pptx file in Angular 2, I am looking for a way to convert my byteArray response into a Blob Object. While I have successfully converted it into image and pdf formats using the code snippet below:
var blob = new Blob(resp, {type: 'application/pdf'});I'm now seeking guidance on what type should be specified for ppt or pptx conversion. Any additional details that need to be included would also be appreciated.
If you need the MIME Types for Microsoft PowerPoint, here they are:
application/vnd.ms-powerpoint
application/vnd.openxmlformats-officedocument.presentationml.presentationIf you come across this and need to categorize it for TypeScript, here's how I approached it:
export type ReportGenerationFormat = 'PPT' | 'WORD' | 'PDF';
interface ReportFileType {
extension: string;
mimeType: string;
}
/**
* List of file name extensions with their corresponding MIME Types.
* PPT is a closed format used before PowerPoint 2007.
* PPTX is an open format introduced since PowerPoint 2007.
* PDF is universally known as Portable Document Format.
* DOC refers to Microsoft document format pre-Word 2007.
* DOCX represents newer versions of Microsoft Word documents.
*/
export const ReportFileTypes: Record<string, ReportFileType> = {
PPT: { extension: '.ppt', mimeType: 'application/vnd.ms-powerpoint' },
PPTX: { extension: '.pptx', mimeType: 'application/vnd.openxmlformats-officedocument.presentationml.presentation' },
PDF: { extension: '.pdf', mimeType: 'application/pdf' },
DOC: { extension: '.doc', mimeType: 'application/msword' },
DOCX: { extension: '.docx', mimeType: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' },
};
Simply import the constant and leverage it using the fileType parameter, such as:
