Convert JSON Format to OTP in Android

Parse JSON format to OTP in Android Applications without using Microsoft^® PowerPoint

Using Aspose.Total for Android via Java, you can easily convert JSON format to OTP in your Android applications. This two-step process involves using Aspose.Cells for Android via Java to parse JSON to PPTX, and then using Aspose.Slides for Android via Java to convert PPTX to OTP.

Aspose.Cells for Android via Java is a powerful API that enables you to parse JSON to PPTX. It provides a wide range of features such as creating, editing, and converting spreadsheets. It also supports a variety of formats, including XLSX, XLS, ODS, CSV, and HTML.

Aspose.Slides for Android via Java is a powerful API that enables you to convert PPTX to OTP. It provides a wide range of features such as creating, editing, and converting presentations. It also supports a variety of formats, including PPTX, PPT, ODP, and PDF.

Both APIs come under the Aspose.Total for Android via Java package. This package provides a comprehensive set of APIs for developing Android applications. It includes APIs for manipulating documents, spreadsheets, presentations, and images. It also includes APIs for working with barcodes, email, and PDF.

By using Aspose.Total for Android via Java, you can easily convert JSON format to OTP in your Android applications. This two-step process involves using Aspose.Cells for Android via Java to parse JSON to PPTX, and then using Aspose.Slides for Android via Java to convert PPTX to OTP.

Convert JSON Format to OTP in Android

Create a new Workbook object and open JSON file
Save JSON as PPTX using save method
Load PPTX document by using Presentation class
Save the document to OTP format using save method

Get Started with Android via Java APIs

You can easily use Aspose.Total for Android via Java directly from Maven and install libraries in your app.

Alternatively, you can get a ZIP file from downloads .

	// open JSON file using Workbook object
	Workbook workbook = new Workbook("input.json");
	// save resultant file in JSON-TO-PPTX ormat
	workbook.save("pptxOutput.pptx", SaveFormat.AUTO);
	// instantiate a Presentation object that represents a PPTX file
	Presentation presentation = new Presentation("pptxOutput.pptx");
	// supports PPT, POT, PPS, POTX, PPSX, PPTM, PPSM, POTM, ODP, and OTP file formats
	// save the presentation as PPT
	presentation.save("output.ppt", com.aspose.slides.SaveFormat.AUTO);

Set Layout and Convert JSON Format to OTP in Android Applications

Furthermore, the API allows you to parse JSON to OTP with specified layout options. In order to specify the layout options, you can use JsonLayoutOptions class. It allows you to process an array as a table, ignore nulls, ignore array title, ignore object title, convert string to number or date, set date and number format, and set title style. All of these options allow you to present your data as per your needs. The following code snippet shows you how to set the layout options.

	// create a blank Workbook object
	Workbook workbook = new Workbook("input.json");
	// access default empty worksheet
	Worksheet worksheet = workbook.getWorksheets().get(0);
	// read JSON file
	String jsonInput = new String(Files.readAllBytes("SampleJson.json"));
	// set JsonLayoutOptions for formatting
	JsonLayoutOptions layoutOptions = new JsonLayoutOptions();
	layoutOptions.setArrayAsTable(true);
	layoutOptionssetConvertNumericOrDate(true);
	layoutOptionssetIgnoreArrayTitle(true);
	layoutOptionssetIgnoreNull(true);
	layoutOptionssetIgnoreObjectTitle(true);

	// import JSON data to default worksheet starting at cell A1
	JsonUtility.importData(jsonInput, worksheet.getCells(), 0, 0, layoutOptions);

	// save resultant file in JSON-TO-PPTX ormat
	workbook.save("pptxOutput.pptx", SaveFormat.AUTO);

	// instantiate a Presentation object that represents a PPTX file
	Presentation presentation = new Presentation("pptxOutput.pptx");
	// supports PPT, POT, PPS, POTX, PPSX, PPTM, PPSM, POTM, ODP, and OTP file formats
	// save the presentation as PPT
	presentation.save("output.ppt", com.aspose.slides.SaveFormat.AUTO);

Convert JSON Format to OTP with Watermark in Android Apps

Using the API, you can also convert JSON to OTP with watermark. In order to add a watermark to your OTP document, you can first parse JSON to PPTX and add a watermark to it. In order to add a watermark, load the newly created PPTX file using the Presentation class, loop through all slides, add text using addTextFrame, set all the relevant options like color, fillType and more and can save the document to OTP.

	// open JSON file using Workbook object
	Workbook workbook = new Workbook("input.json");
	// save resultant file in JSON-TO-PPTX ormat
	workbook.save("pptxOutput.pptx", SaveFormat.AUTO);
	// instantiate a Presentation object that represents a PPTX file
	Presentation presentation = new Presentation("pptxOutput.pptx");

	for(ISlide slide:pres.getSlides()){
	IAutoShape ashp = slide.getShapes()
	.addAutoShape(ShapeType.Rectangle,50, 50, 500, 500);
	ashp.addTextFrame("Watermark Text");

	ashp.getTextFrame().getParagraphs().get_Item(0).getPortions()
	.get_Item(0).getPortionFormat().getFillFormat()
	.setFillType(FillType.Solid);
	ashp.getTextFrame().getParagraphs().get_Item(0).getPortions()
	.get_Item(0).getPortionFormat().getFillFormat()
	.getSolidFillColor().setColor(Color.GRAY);
	ashp.getTextFrame().getParagraphs().get_Item(0).getPortions()
	.get_Item(0).getPortionFormat().setFontHeight(25);

	// Change the line color of the rectangle to White
	ashp.getShapeStyle().getLineColor().setColor(Color.WHITE);
	ashp.getShapeStyle().setLineStyleIndex(LineStyle.ThinThin);

	// Remove any fill formatting in the shape
	ashp.getFillFormat().setFillType(FillType.NoFill);

	ashp.setRotation(-45);

	ashp.getAutoShapeLock().setSelectLocked(true);
	ashp.getAutoShapeLock().setSizeLocked(true);
	ashp.getAutoShapeLock().setTextLocked(true);
	ashp.getAutoShapeLock().setPositionLocked(true);
	ashp.getAutoShapeLock().setGroupingLocked(true);
	}

	// supports PPT, POT, PPS, POTX, PPSX, PPTM, PPSM, POTM, ODP, and OTP file formats
	// save the presentation as PPT
	presentation.save("output.ppt", com.aspose.slides.SaveFormat.AUTO);
