I'm developing an application that as to export a dataset to excel, this dataset have 3 tables and the relation between them, I would like to export this to a single excel sheet where for each parent table there is a '+' sign that when expanded shows the child values related to it. To export a single table to excel I know how to do it, but to create this type of relation I have no idea how to do it, do I have to create a macro on the excel file?
I use a DevExpress Reports or a ActiveReports for this. I create a normal report and next i save it in xls, and Done. Its very complicated to this using us code. Its more easy to use a third-party components
There's a free tool: https://closedxml.codeplex.com/ to create XLSX outputs from code.

Excel Reference Image to import sequence data to NI TestStand
Please I need help to Import excel data to NI TestStand sequence file. This excel file for just reference only.
Please let me know if there is any confusion. Thanks
Is the data you are referring to in the Excel file properties? Or did you want to actually create Test Steps from Excel file?
If it's properties to load, then use the Property Loader Step. To make it easier, you can do an export which will create the XML layout which you can modify the data with the one in the Excel.
As far as creating a Test Step based on Excel file, that's not how TestStand works.
You can do this with Import Properties.
I would first create a test sequence as a model and export the properties from it. Then you can use that as a template to import the properties you have in your excel file.
From what I see from your example though. It may be easier to just manually create the sequences and steps, if that's all there is. If you have to create 300 steps or sequences it may be a better idea to utilize loops or create a module.
I am trying to including a table or specific range from one sheet into another sheet as an image/picture.
In Excel it is done by selecting the entire table from sheet2 and then on sheet1: Paste Special - Linked Picture.
Is there a way to get this done using C#? I am developing a project which requires this task.
I'm not sure about converting the contents to a picture, but you can read and write to/from a spreadsheet using the Open XML SDK (link). I've used it to manipulate Word documents, but I imagine it functions similarly for spreadsheets.
I used store a data into the DataTable and wants to create a Pivot Table using this data.
I have gone through many posts and also read the Microsoft's documentation on creating Pivot table through Open XML but couldn't get the solution. Can anyone please post some code to create Pivot table.
Thanks in advance.
Install the Open XML SDK, it contains a tool called Open XML SDK Productivity Tool.
How to use it:
Open Excel and create a file containing a Pivot table. Save it and open it with the Productivity Tool. In this tool is an option to 'Reflect the code', that way you can see how to create the same Excel by using C# code.
I have a set of Excel spreadsheets with multiple tabs which contains each one table that I need to export as pictures in an automated process (I have dozens of such files to process).
While I could "manually" select the table, copy and paste them as image in another software, I need to industrialize this process to save time.
What would be the best approach using .Net or any builtin Excel feature?
Thanks
Check this question.
Programmatically (C#) convert Excel to an image
It looks like they're doing what you need?
Think I would use a small C# apop to do it - that assumes that you have a one off task and don't want to mess about with Excel templates or global excel macros and opening each spreadsheets etc.
I would do it like this:
dump all my excel docs in a single folder.
open up each doc in the folder in C# app
iterate each tab
If data capture data for all used ranges (from A1 to the whatever the bottom right cell is) - for any embedded charts pull them off as well
If chart pull it off
dump each to the folder as an image prefixed with the excel doc name and some iterative suffix like _chat01 _data01
How to rwead it ina and convert to image? See here => http://csharp.net-informations.com/excel/csharp-excel-chart-picturebox.htm
Copy all desired cells
Open MS-Paint
Paste
Save as PNG.

you need to find where the "slowness" come in.
