    Overview of WPF SpreadStreamProcessing Library
  • No External Dependencies

    The document model has no external dependencies on third-party software or UI. Users are able to process Microsoft Excel supported documents even without having Microsoft Excel, Microsoft Office or any other external library installed on the client or server.

  • Fast and Memory-Efficient Spreadsheet Creation

    The library dynamically writes the document content into a specified stream for memory efficiency. Each time an exported object is disposed, the set values are written into the stream. This allows you to create large documents with excellent performance.

  • Grouping

    The WPF SpreadStreamProcessing grouping feature allows placing rows and/or columns in sections which could be expanded and collapsed by users—quite useful when we want to hide the complexity of the detailed data and present just the summary of it, while still keeping it available for users to see. Use the SpreadStreamProcessing API to set the outline level of rows/columns when creating them.

  • Cells

    Cells are the basic unit of data in worksheets—they are the intersection point of rows and columns. The SpreadStreamProcessing for WPF API provides multiple properties for defining the value and formatting options of cells. You can apply different settings for fill, border, font family and size, wrapping, as well as use various format strings, making it easy to work with different types of data.

  • Formulas

    In addition to setting the various cell properties when creating cells in a worksheet, the cell value can also be set to any formula supported by the OpenXML format. This will guarantee that when the document is open in any spreadsheet application complying with this format, the formulas will be appropriately evaluated.

  • Style Cells

    A cell style is a predefined set of formatting options such as border options, fonts and format strings, that allows you to reuse it across the whole document during cell creation. In this way you can ensure consistency in cell appearance across your spreadsheets.
