Aspose.Cells for Reporting Services allows you to export native Excel reports in Microsoft SQL Server 2005 Reporting Services. Unlike the built-in renderer for Excel based reports, Aspose.Cells for Reporting Services provides an extended feature set and allows RDL reports to be converted to: Excel 97-2003 binary XLS format, SpreadsheetML, or the Excel2007 XLSX format. With the Aspose.Cells Report Designer tool, users can design and deliver reports into MS Excel directly without using Visual Studio IDE.
Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. It runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems, and should run on pretty much any system with a decent C++ compiler. Xpdf is designed to be small and efficient. It can use Type 1 and TrueType fonts.
4Suite is a Python-based toolkit for XML and RDF application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, RDF, XSLT, XInclude, XPointer, XLink, XPath, XUpdate, RELAX NG, and XML/SGML Catalogs. Layered upon this is an XML and RDF data repository and server, which supports multiple methods of data access, query, indexing, transformation, rich linking, and rule processing, and provides the data infrastructure of a full database system, including transactions, concurrency, access control, and management tools. It also supports HTTP, RPC, SOAP, and FTP, plus APIs in Python and XSLT.
