knroc [OR, USA] 03-Jan-2012Review: 

I had a requirement to create a web-based application that would create two pivot tables. The data source was SQL Server and the user had to be able to filter the data before populating the workbook. The XlsIO solution was both elegant and simple. I used XlsIO to open my existing workbook (which contained the pivot tables), populated a sheet with the desired data, reset the data source range of the pivot tables to use the new data and saved the new workbook for the user to download. I had never used XlsIO before, yet by looking at a couple samples, their online documentation and some posts in their support website I was able to complete the project in a few hours instead of the couple weeks that I had thought it would take.

I did run into one problem - one of the argument types to a function didn't match the documentation - it wanted an int[] instead of an int. The routine still worked by setting x[0] to the value I needed - I figured that it must have been an oversight so I submitted a bug report. The support experience was really top quality. Syncfusion communicated at every step of the process. A support tech told me that he had received the report and was looking at it and gave me a date by which he would tell me if he could reproduce it. That date was met and he then told me that the bug had been forwarded to the devs and gave a date that it would be fixed. That date was also met and I was given a link so I could download the fix. The great thing was that the fix wasn't just a dll - it was wrapped in an installer that updated the proper files and also put them in the GAC. After a few days, the support tech emailed me to verify that the fix had actually solved my problem.

The communication and attention I received made me feel like Syncfusion cared about me as a customer and that they take great pride in their products.

I've been using Syncfusion Essential XlsIO for over 7 years now. I recently started a new project and needed to be able to import data from differently formatted Excel documents. XlsIO has a great method to return the contents of an Excel sheet as a DataTable.

I ended up having a problem opening up a .xlsx version of an Excel spreadsheet. I posted my problem to Syncfusion support and within hours Sridhar replied back with a simple solution for me.

I have nothing but good to say for Syncfusion and their product Essential XlsIO. We also use their GridGrouping control and are very happy with it.

Kjell [Sweden] 09-Jun-2011Review: 

Our previous excel solution was feature incomplete - the reports that were generated by the excel export engine did not look anything like the reports we produced on the web. After switching to XlsIO we can produce excel reports that are nearly identical to the ones we produce on the web.

Also, when we ran into a bug close to a release, the SyncFusion support responded quickly and delivered a hotfix within a few days, allowing us to release on schedule.

I can really recommend this product and the company behind it.

We are using Syncfusion GridGrouping, Grid controls, DockingManager and a couple of other controls. All these have a rich functionality and are very flexible due to their elegant design. As for the support, I need to mention that we are using old 4.x version (while the current version is 9.x)., so the support team often forced to merge fixes from latest versions back to this old one. But even in these, pretty unusual conditions, we are still getting very valuable help from Syncfusion!

Tukaram.Thatikonda [NJ, USA] 27-Apr-2011Review: 

Initially when we started, we were looking for a 3rd party product that can produce rich excel reports programmatically. Essential XlsIo from Syncfusion was one of the product that we evaluated. The product didn't let us down and I would definitely recommend this product since it was easy to use, good feature list and the sample provided was a good starting point.

Syncfusion should come up with some good documentation and sample example code but the support team was excellent. Response and followup was great!

Thank you Syncfusion for your hard work. Long way to go!!

I have been using Syncfusion XlsIO for just over 3 years and am very happy with its performance, scalability and sheer number of features.

I used to use Excel.Application via com-interop in .Net and suffered many issues over time so I needed a solution that would give me better reliability and ideally better performance. XlsIO delivered!

The documentation is very good and the software gets regular updates throughout the year.

From time to time I have a need to contact product support to either report an issue or ask a 'how-to' question. I find the web-based support easy to use and the response time is pretty good. I have sometimes been given patches to fix an issue without having to wait for the next release which I appreciate.

anton.yakushin [MA, USA] 06-Apr-2011Review: 

This is by far the very best component for dynamic Excel Spreadsheet generation on the market. Our company has tried several alternatives, but nothing compares to the ease of use and performance of XlsIO. For programmers, usability is similar to using the Office11-Office14 references in VB and C#.NET programming, except SyncFusion has found a way to make it even more intuitive and faster to work with. In fact, some functionalities are easier to do with SyncFusion's XlsIO than VBA in Excel, and the fact that they support all formats 2000-2010 was extremely helpful to our clients. The XlsIO code is ready-to-go for generating virually any file and sending it right into the reponse stream! SyncFusion's tech team even helped walk me through getting everything set up, and were very friendly and helpful. 5 stars!

William [South Africa] 04-Feb-2011Review: 

We've been using this for our Excel file processing for the past couple of years now. If we're not importing massive data sets from Excel files, we're exporting to custom specialised reports. The main factor for us is performance, especially since we work with large files and do a lot of processing in the files while generating... and XlsIO works faster than any of the other tools I've tested. I'm using a very popular grid control from another party and wrote an export to Excel extension function for the grid using XlsIO and it works at least 3 times faster than the grid's internal SaveExcel function. They're also up to date with the latest file formats as Excel versions get released and upgrades are available 4 times a year.
Had a couple of small issues before, but the issues were fixed in a couple days and a patch was supplied to me.

I use the Syncfusion XlsIO for
internal windows applications and external web applications to create excel workbooks.
It integrates well with vb.net and makes reading from and loading and manipulating
Excel sheets fairly easy.
Support is available in about 2 days.

Ketals [MN, USA] 02-Feb-2011Review: 

We have been using Xlsio for last 3 years. Before buying syncfusion we evaluated many 3rd party products and worked with their support team during the evaluation period. Finally we chose Syncfusion Xlsio component. No other product came close to syncfusion. Users in our organization use MS office excel for their day to day task. The excels has macros, formulas, graphs, support creating/manipulating excel sheets on fly ,etc. Apart from XLSIO other advantage we found using Syncfusion.Calculate.Base api (which comes with the Sycnfusion back office) was when we had formulas which are in strings and needs to be parsed inorder to calculate the value.
The driving factor in buying Syncfusion xlsio was that we needed to get away with office installation on servers and use xlsio api to develop applications that worked with the excel file in a very short time frame. The advantage of using xlsio api is that it is very easy to use , the support docs are well documented, the support staff is pretty quick in responding to issues.

I would definetly recommend Syncfusion XlsIO to anyone that needs to use Excel or build applications around excel in their organization.

mweaver [MA, USA] 25-Oct-2010Review: 

Several years ago, we needed a way to create Excel workbooks on-the-fly as part of our EQuIS (Environmental Quality Information System) application. Microsoft Excel automation was not an option because we needed the functionality to work on a server platform (which is not supported for Excel automation). Using Excel automation on the desktop platform was excruciatingly slow. We were looking for a .NET managed component and found Syncfusion XlsIO. The product was easy to use, worked in all the desired environments, an performed better than expected (it is very fast). We have continued to use Syncfusion XlsIO over several major version releases and have expanded its use within our own product. Syncfusion technical support has always been responsive and helpful. I have recommended Syncfusion XlsIO to several of our clients, who have also had positive experiences with Syncfusion.

kloko [Germany] 25-Aug-2010Review: 

We're using the Syncfusion XlsIO in our trading system for external reporting (in excel) and for a lot of other internal document handling (special excel files) since 2009. In this year we have adapt the most of our modules to the new version 8. The benefit of using the XlsIO is that we're completly independend of the local installed excel version. We are handle complex excel sheets with a high amount of data.

If we have problems the Syncfusion support needs mostly one or two days to identify and if it's required to fix issues. Requests for implementing new functionality are always welcome and mostly in the next or in the next but one major release available.

Steve Jacobs [USA] 28-Jun-2010Review: 

Syncfusion XlsIO has been invaluable for several of our clients that use Excel forms as their primary means of data input. XlsIO enables us to easily extract data for expanded manipulation and analysis in our clients' .NET applications. Further, the intuitive XlsIO API has allowed us to spend our time on application development, rather than a component learning-curve.

I would highly recommend Syncfusion XlsIO to anyone that needs to use Excel within a .NET environment.

seanduffy [USA] 25-Jun-2010Review: 

I needed a solution that allowed me to customize Excel files for my startup, a company that sells a Microsoft Excel training tutorial (picture a book written in Excel with interactive exercises). Each file needed to be processed specifically for each user, embedding their information, and then locking it. I spent a lot of time researching all of the options and Syncfusion was the only that was able to handle the complexity of my document (it uses lots of settings, functions, and formats).

We ran into a few problems on the way and Synfusion support was super quick to help debug what was going on. I highly recommend Essential XlsIO.

rajanikantk [USA] 18-Jun-2010Review: 

With Syncfusion Essential Tools and Essential XlsIO, we allowed application developers to spend more time adding cutting-edge business functionality, and less time writing infrastructure and process-level code. We needed on-demand, dynamic excel outputs for the data in grids to be built in a crucial framework that was being used by about twenty different investment bank applications and this saved a ton of time and cost collectively. This was the perfect solution to go along with their top performing grids.

Paul.Conway [United Kingdom] 14-Aug-2008Review: 

I have been using XlsIO for several years now. We had a need to create complex spreadsheets on the fly to deliver information to clients and found that it fitted the job perfectly.

We now use it extensively in all our products where there is a need to create excel reports - this includes both web and desktop applications.

I have found the technical support (when needed) to be helpful.
