The Syncfusion Excel Library (Essential XlsIO) is a feature-rich and high-performance Blazor Excel library that allows you to add robust Excel functionalities to any Blazor application. It allows you to create, read, and edit Excel documents programmatically without Microsoft Office dependencies. This library also offers functionality to import and export data, visualize data as charts, tabulate data, calculate with simple and complex formulas, format cells and values, sort and filter data, protect Excel files, and more.
Optimized for a server environment where speed and low memory usage are critical. It works much faster and consumes less memory than Office automation libraries.
There are no distribution fees, per-server licensing fees, or royalties, making Excel Library very cost-effective.
It’s easy to migrate existing Office automation code to Excel Library since the APIs are very similar.
The library reads and writes all popular Excel file formats including XLS and XLSX. A file can be opened in one format and saved in another format.
The comprehensive API makes it possible to create richly formatted Excel files with elements like text, numbers, formatting, images, charts, and pivot tables. It is also possible to extract any desired piece of information from an existing workbook.
Reports can be designed using Microsoft Excel, and Excel Library can be used to dynamically populate them with data. Final reports can then be saved to an Excel file or exported to other supported formats.
Easily import data from common data sources like arrays, data tables, and collection objects into an Excel worksheet.
Data in an existing worksheet can also be exported to collection objects and nested classes.
Data sorting can be performed based on cell value, cell color, and font color using multiple sorting algorithms.
Excel Library supports various filter options like Top, Top10, and Percent, with different filter types such as custom, combination, dynamic, color, icon, and advanced filters.
Cell data validations can be applied with operators, alert messages, custom formulas, and drop-down lists.
The built-in calculation engine quickly evaluates formula cell values during runtime. It supports over 400 Excel functions.
Named ranges can be used in formulas as substitutes for cell references. The built-in name manager allows adding, editing, and deleting names.
