Digitally Sign XLSB Documents in Java (Code Example)

Add Digital Signatures to XLSB in Java

Add custom digital signatures to XLSB documents in Java based on PFX certificate files. The all-in-one electronic signature API easily integrates with your Java application to give you a personalized document signing experience using a few lines of code.

Instantiate Signature with (XLSB) as input document
Instantiate DigitalSignOptions object with certificate & password details
Call sign method of Signature class and pass DigitalSignOptions to it

Work with XLSB Signature API

You require GroupDocs.Signature namespace to digitally sign documents in Java & J2SE applications. Use signature manipulation features to customize sign, search and signature verification processes, manage eSignature colors, styling and overall appearance.

Get the respective assembly files from downloads or fetch the whole package from Maven to add ‘Conholdate.Total` directly in your workspace.

Add Text Signatures to XLSB in Java

Add customized text signature to a XLSB document in Java using advanced text settings such as font color, size, name, text alignment and border adjustment.

Create a new instance of Signature class and pass input document
Instantiate the TextSignOptions object and specify text signature options
Call sign method of Signature class instance and pass TextSignOptions to it

eSign Remotely Located Documents

The document eSign API enables you to load & display remotely located documents from various cloud document storage sources such as stream, local disk, URL, FTP, Amazon S3, and Azure Blob storage. Using document information extraction feature - fetch the basic information about the source document file (XLSB) along with extracting other valuable document information such as file type, file size, pages count, page height and width etc.

Add Image Signatures to XLSB in Java

Using Conholdate.Total for Java - insert custom image as an electronic signature to a XLSB document in Java. Add company logo, stamp icon or name using different colors and text effects.

Create a new instance of Signature class and pass input document to it
Instantiate the ImageSignOptions object and specify image signature options
Call sign method of Signature class instance and pass ImageSignOptions to it

Image Representation of Document Pages

Apply digital signatures to a wide range of document formats and generate the image representation of the already signed document pages in PNG, JPG or BMP formats. You can easily preview the complete document as a whole or choose to display some specific pages based on page numbers or page ranges.

Using advanced document previewing features - easily hide digital signatures from the signed documents while generating the document preview.

What is XLSB file format?

The XLSB file format is a binary file format used for Microsoft Excel workbooks. Unlike the XLSX and XLSM file formats, which are based on the Open XML format, XLSB is a binary format that stores data in a binary structure. This binary structure allows for faster file processing and improved performance compared to the XML-based formats.

XLSB files contain spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. The binary format optimizes storage and calculation efficiency, making it well-suited for large datasets and complex calculations. It also provides better data integrity and recovery capabilities, as the binary structure reduces the risk of file corruption.

Due to its binary nature, XLSB files are not easily readable or editable by humans. They are primarily intended for use by Excel and other applications that can read and process the binary format. However, Excel provides full compatibility and support for opening, editing, and saving XLSB files.

The advantages of using XLSB files include faster file operations, reduced file size compared to XML-based formats, and improved performance in terms of opening, saving, and recalculating complex workbooks. XLSB files are particularly useful for workbooks that involve large amounts of data or complex formulas.
