แอปแปลง POTX to XLSX ออนไลน์ฟรีผ่าน swift

วิธีแปลง POTX to XLSX เป็น Swift: ตัวอย่างโค้ดทีละขั้นตอน

// กำลังแปลง POTX เป็น HTML
let outPath = "file.POTX"
SlidesAPI.savePresentation("flie", "HTML", outPath, nil, "password", "TempSlidesSDK") { (result, error) -> Void in
    XCTAssertNil(error)
    XCTAssertNotNil(result)
    SlidesAPI.objectExists(outPath) { (exists, error) -> Void in
        XCTAssertNil(error)
        XCTAssertNotNil(exists)
        XCTAssertNotNil(exists!.exists)
        XCTAssertTrue(exists!.exists!)
        expectation.fulfill()
    }
}

// กำลังแปลง HTML เป็น XLSX
let cellsApi = try CellsAPI(clientId: "YOUR_APP_SID", clientSecret: "YOUR_APP_KEY");
let expectation = self.expectation(description: "testcellsSaveAsPostDocumentSaveAs")
let name:String = file.HTML

let newfilename:String = "file"
let isAutoFitRows:Bool? = true
let isAutoFitColumns:Bool? = true
let folder:String = TEMPFOLDER

    CellsAPI.cellsSaveAsPostDocumentSaveAs(name: name, saveOptions: saveOptions, newfilename: newfilename, isAutoFitRows: isAutoFitRows, isAutoFitColumns: isAutoFitColumns, folder: folder, storageName: storageName)
    {
        (response, error) in

            let errorinfo = self.GetErrorDataInfo(error: error as! ErrorResponse)
            print("error info: \(errorinfo!)")
            return
        }

        if let response = response {
            expectation.fulfill()
        }
    }
