• No dependency on Excel or Calc installation (no OLE)
• Full unicode support even for non-unicode Delphi versions (D7, D2007 etc.)
• Write-On-The-Fly and Read-On-The-Fly: export and import huge tables without the need to store the whole document in memory.
• Reasonably fast (see performance table below).

Officially supported platforms

• Delphi 5, 6, 7, 2005, 2006, 2007: VCL + full unicode support thanks to WideString.

Template Engine

• Currently only loading of XLSX/XLTX and XLS/XLT templates is supported.
• Automatically replace cell values and modify cells.
• Automatically add and process rows as they are defined in the template.
• Save the generated template in all formats OExport supports: XLSX/ODS/XLS/CSV!

Feature Overview

See the following files for a fast feature overview. These files have been directly exported with OExport:

• XLSX: oexport-fulldemo.xlsx
• ODS: oexport-fulldemo.ods
• XLS: oexport-fulldemo.xls

You can generate those files with the demo application you find in the FREE package (see download tab).
They have not been edited after the export in any way.
Please note that XLS exporter doesn’t support images and charts and therefore you won’t see them in the exported XLS file.
The full source code that was used to generate them
can be obtained from the documentation.

The limits are the following:

Performance

The performance of OExport may vary on used compiler. The best figures are reached
with Delphi 2009 and newer.
The following times were measured on an old laptop from 2007
(Intel Core 2 Duo, 1.8 GHz, 4.0 GB RAM, Win 7 32bit).
Files consisted of 1 million string cells
with shared strings table (SST) either off or on.

OEXPORT LICENSE INFORMATION
===========================


Copyright (C) 2011-2017 Ondrej Pokorny
  http://www.kluug.net

This license is applicable to all files distributed in this archive if not
stated differently.
The commercial part of the license text (FULL version) applies to orders
after March 14th, 2017.


*** BEGIN LICENSE BLOCK *****

OExport 2.x LICENSE
-------------------

 1) You may use OExport if:
     a. You use the FREE version.

        OR

     b. You have a commercial license for the FULL version.

 2) Limitations of the FREE version
     a. There are no limitations per workplace. You can use OExport FREE
        both for commercial and non-commercial purposes.

     b. Only the first worksheet will be exported or imported and a maximum
        of 40 rows and 10 columns.

     c. You may not modify, decompile, disassemble, reverse engineer or
        translate OExport FREE.

 3) Limitations of the FULL version
     a. Only developers who work for the license holder company may use OExport.
        That includes freelancers but only in projects assigned to them by the license
        holder company.

     b. The number of active developers who use OExport may not exceed the total number
        of licensed developers that the license(s) of the holder company provide(s) for.

 4) Transfer of FULL version licenses

     a. Licenses may be transferred to new developers who work for the
        license holder company if all other requirements are met (especially point 3b).

     b. The license may be transferred only as a whole to a different company.
        Example: you buy a 3-developer license. You may transfer it completely to
        a different company. You may not split the license and transfer 1-developer
        license to a different company and keep 2-developer license.

 4) License validity

     a. The license is perpetual.

     b. You get 2 years of free updates and new releases, starting from the day
        of purchase. After this period you can order extra 2 years of updates
        (starting from the day of update expiration) for 60% of the license price
        at the moment of update expiration.

 5) You may NOT use OExport for:
     a. Writing libraries and applications that are in direct or indirect
        competition with OExport or tools whose main purpose is providing OExport
        functionality. An example would be to build a public XLSX- ODS- or
        XLS-Export library or a conversion tool etc. OExport functionality
        has to be an extension to an existing application (e.g. export in
        an accounting software).
        If you need a special license, please contact the author.

 6) Redistribution of the source code and the DCU's
     a. OExport source code and DCU's may not be redistributed on any kind
        of media or offered for download on any internet server without
        the author's explicit permission.

 7) Redistribution in binary form
     a. If you do not have a FULL commercial license, you have to attribute
        OExport in e.g. the About Dialog of your software.
        The attribution must contain the name ("OExport") and my homepage
        ("http://www.kluug.net").

     b. If you do have a license for the FULL version, no attribution is required.

 8) Additional software licensed with OExport
     a. If you purchase OExport, you also get a special OXml commercial license.
        This license allows you to use OXml only as part of OExport (because
        OExport uses OXml for handling XLSX and ODS files).
        You are not allowed to use OXml separately - in this case you have
        to obtain OXml commercial license as well.
        This paragraph applies to OXml which is located in OXml directory.

 9) Limited Warranty
     a. THIS SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
        EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
        WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
        THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE SOFTWARE IS
        WITH YOU. SHOULD THE SOFTWARE PROVE DEFECTIVE, YOU ASSUME THE COST OF
        ALL NECESSARY SERVICING, REPAIR OR CORRECTION. IN NO EVENT SHALL
        KLUUG.NET OR ANY OTHER PARTY WHO MAY HAVE DISTRIBUTED THE SOFTWARE AS
        PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,
        SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
        INABILITY TO USE THE SOFTWARE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
        OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
        PARTIES OR A FAILURE OF THE SOFTWARE TO OPERATE WITH ANY OTHER
        PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
        POSSIBILITY OF SUCH DAMAGES.
