Overview

A Java Excel Spreadsheet API library is a programming interface allowing Java developers to programmatically create and manipulate Excel documents at scale. Document Solutions for Excel, Java Edition (DsExcel Java) is a solution that allows developers to import/export, create reports & templates, and deploy spreadsheets across Java applications.

The Benefits of a Java Excel API Library

Fast and Efficient

Save memory and time with the lightweight API architecture. The more rows in the spreadsheet, the faster our API is by comparison. Integrate with client-side Document Solutions Data Viewer to load and view the generated Excel file.

Flexible Themes and Components

Empower users with customizable themes, configurable components, summary data, custom styles, embedded drawing objects, integrated calculation engine, and more.

Seamless Excel Compatibility

Lose nothing on import. Pivot tables, comments, charts, conditional formatting, data validation, filters, formulas, shapes, pictures, slicers, sparklines, and tables stay intact.

Develop Excel Spreadsheets in Java 8.0+ for Windows, Linux, and Mac

Create lightning-fast spreadsheets in cross-platform apps with this intuitive Java API.

Document Object Model

The interface-based API allows you to import, calculate, query, generate, and export any spreadsheet scenario. With the VSTO-style API, you can create custom styles using the same elements as VS Tools for Office.

Deploy Java Spreadsheets to the Cloud

Cloud-based deployment means you can be everywhere - with Maven and DsExcel Java, you can deploy to Azure, AWS, and AWS Lambda.

Import only data only from Excel files using Java Excel API

Import Data Only from Excel Files

Try new ImportData() function to import just the data from Excel files without loading the whole object model. Faster and efficient way to import data.
