I hope to get a solution here. I am completely new to R and really all i need it for is to extract data from power query and append it to an existing csv file. The only export approach that i have come across only works for exporting to the local c drive as per my example below. This approach however does not work for files in sharepoint with a URL. Can you please advise on a solution? Thanks
write.csv(dataset,"c:\\documents\\test.csv ,append=true")

I have a simple concept where I want to retrieve a table from a website and use it in that exact format. This can be for example imported into Excel.
This is the website that I want to get the table from:
http://www.dota2.com/leaderboards/#europe
This is the API that the website uses to get the data:
http://www.dota2.com/webapi/ILeaderboard/GetDivisionLeaderboard/v0001?division=europe
In all the ways I attempted to get the data from the website, it is poorly formatted into one line, and I was wondering what is the best way to format/use this data through code or other tools available. I have tried:
Excel web importing
Writing a simple VB program to read each line (but it reads it all as one line)
Copy and pasting the table to Notepad to try format it by line(still one single line)
Any tips/suggestions regarding any form of website data retrieving is very much appreciated.
I have a huge dataset value in JRDatasource object and am not able to export it to Excel as it will give me memory out of space error. So am planning to split the JRDatasource object and export the data part by part. Any idea or suggestion on how to implement this? Or any other way suggested also fine for me. Thanks in advance.
I dont know much about JRDataSource, but I'll offer another solution.
Take a look at Apache POI library which enables you to create excel files on-the-fly.
So you can read from the data source element by element and persist them on a excel file.
I want to use Neo4j to store a number of graphs I created in python. I was using Gephi for visualization, and I thought the export to Neo4j plugin would be a very simple way to get the data across. The problem is that the server is seemingly not recognizing the neostore...db files that Gephi generated.
I'm guessing I configured things incorrectly, but is there a way to fix that?
Alternatively, I'm also open to importing the files directly. I have two files: one with node titles and attributes and another with an edge list of title to title.
I'm guessing that I would need to convert the titles to ids, right? What would be the fastest way to do that?
Thank you in advance!
If you have the file as tab separated csv files, feel free to import them directly. There are some options, check out this page: http://www.neo4j.org/develop/import
Especially the CSV batch importer can help you: http://maxdemarzi.com/2012/02/28/batch-importer-part-1/
Or if it is just a little bit of data, use the spreadsheet approach: http://blog.neo4j.org/2013/03/importing-data-into-neo4j-spreadsheet.html
Please report back if you were successful.
I used Gephi to generate a neo4j store file directory in the past - it worked like a charm...
I assume you did delete the default graph.db directory and renamed your gephi-generated directory to graph.db? That worked for me...
Generating normal columnar data in excel file is quite easy but does any one of you have generated excel files having datas in different blocks placed in different sheets and beautifully formatted without having to manipulate the excel file using COM [which i want to avoid]. Any ideas would be really helpful.
The output excel file should be compatible with Office 2003 + office 2007
Don't know exactly (as I've Excel installed on both my dev and server machines) but I think ExcelPackage can do the trick.
Check spread sheet gear, with the help of spread sheet gear I have created excel with very good formating as well

If you're not creating many spreadsheets, or don't wish to buy a product which makes this easier, your solution might be to use templates.
Create a excel document, in the style you want, then save it as xml.
Then modify the xml document as you like, using place holders or whatever, to generate your documents.
This works for simple reports where you don't want to use a 3rd party product.
For anything else I'd recommend a product specializing in this.
You can check SmartXLS for .net.
Anyone know of some code out there that does this already? I have a bunch of pages with data grids on them in an admin website they want to export them to Excel, was hoping someone had this written already - or if not I'll post mine when I am done.
Excel can open files in the format of CSV and XML - it can also generate the schema file.
if you have data grids then the chances are you have data sets.
There is a method on the dataset to output as XML.
you probably have to use an xmlWriter to save the file.
