I am using existing CSV editor available in eclipse, but which is adding new columns only at the end. If I want to add a new columns in the middle of existing columns, I need to edit in CSV source format type i.e. with comma separate format and feed all the data, which is very difficult.
I found one good utility tool. CSV pad.
Download this , it is helping me to add columns where ever i want, not only at the last.
Open the desired file from the location , then edit as you want, save it.
It wont effect the format. [you can direct open eclipse workspace testdata folder too from this tool and edit the input csv file].

When I import a csv to Tableau, it gets the same format of the original csv file (a single column with every label on it). How can I make Tableau separate the columns based on commas?
I can't see why this is happening, since in every tutorial I checked Tableau already converts the .csv to a tabular format.
Here's what I get
Note: I'm using Tableau's trial version.
Sometimes when you open a csv in Excel it can mess with the formatting like your image shows. If you think you opened it in Excel before connecting, try downloading your source again and connecting first with Tableau. If that doesn't work, I happen to have this dataset in a .tde if you would like to use that. vgsales.tde
Edit: Thinking regional settings might be a factor.
Click the dropdown on the right of the data source. Select Text File Properties

Can you match these settings?
I am able to find some information on how to read a csv file on a computer but is there any way I can modify one? In my chrome extension I need to add data to each row one at a time after scraping some websites. Is there any better way then read csv, store data as variable and rewrite is everytime? This becomes problematic when the file gets large. I am looking for a way to “append ” to a existing file or a work around. Any suggestions appreciated.
Update: From comment I see it is not possible to read from file system. But is there anyway to read from within the extension directory? How should I do so if the csv file is included with in the zip file of the extension? Can I access them somehow? Code snippets would be helpful.
I'm in the middle of creating something which might help you. Right now you can upload the CSV file and append a "modifier". You can adjust the code according to your requirement. Here's the repo https://github.com/amanrOnly/CSV_Modifier
I want to create .csv files with the Report Generation Toolkit in Labview.
They must actually be .csv files which can be opened with Notepad or something similar.
Creating a .csv is not that hard, it's just a matter of adding the extension to the file name that's going to be created.
If I create a .csv file this way it opens nicely in excel just the way it should, but if I open it in Notepad it shows all kind of characters and it doesn't even come close to the data I wrote to the file.
I create the files with the Labview code below:
Link to image (can't post image yet because I've got to few points)
I know .csv files can be created with the Write to Spreadsheet VI but I would like to use the Report Generation Toolkit because it's pretty easy to add columns and rows to the file and that is something I really need.
you can use the Robust CSV package on the lavag.org forum to read and write 2D arrays to CSV files.
http://lavag.org/files/file/239-robust-csv/
Calling a file "csv" does not make it a CSV file. I never used the toolkit to generate an Excel file, but I'm assuming it creates an XLS or XLSX file, regardless of what extension you give it, which is why you're seeing gibberish (probably XLS, since it's been around for a while and I believe XLSX is XML, not binary).
I'm not sure what your problem is with the write spreadsheet VI. It has an append input, so I assume you can use that to at least add rows directly to a file, although I can't say I ever tried it. I would prefer handling all the data in memory explicitly, where you can easily use the array functions to add rows or columns to the array and then overwrite the entire file.
lately I've been into combining multiple OpenXML speadsheets via PHPExcel which
showed me that this framework has certain issues which makes it pretty much unusable
for what I want to do (my related SO question).
To make it short: it's hard to guarantee that all formatting features of Excel 2007 will
persist a file merge performed with that particular framework.
Anways, now I'm thinking of a more general approach. I want to open a template XLSX
which contains various formatting and add some plain alphanumeric data worksheets 'at the end' of the workbook.
Is sensefully possible to do the following:
unzip template XLSX
parse XML files
add worksheets
save xml files
rezip files to get valuid XLSX
Any hints or experiences would be highly appreciated.
thanks in advance

I haven't worked with .xlsx too much, but I've altered .docx files by manually adding and editing the XML.
The biggest concern with adding new parts to a document is to make sure you update the .rels files. The best way to figure out what needs to be updated is to create a new .xlsx document in Excel, add a worksheet, save the file and then unzip it to see what has changed. You can also use the DocumentReflector tool that comes with the OpenXML SDK if you want to see the internals of the file without having to unzip it.
I found the OpenXML reference manual very helpful when hand editing files because it tells you what elements you have to keep and what elements are optional to make a valid document. It makes it easier to work with when you can remove some of the extraneous elements that Excel adds automatically.
I have a csv imported into my Hyperion v8.3 bqy file. I have some custom columns and a pivot already created. I just want to refresh the data. In the past, I would hit Process Current and it would direct me to my computer and I could select the csv file to update from. Now it will not do that. It doesn't go to my computer at all.
Any ideas?
Eric,
I'm not a power user but I accomplish the same thing by ensuring that there is a file with the same name in the same location from which the original csv was imported and "Processing All". This allows me to update the data and import it into my bqy and automatically update any reporting based on the csv.
Don't know if this will help or not.

When you import a file as a Section into Hyperion, it maintains a link to the existing file for the exact path and file name. When that link is broken and that section gets a Process or Refresh command, is the only time it will prompt you for a new file. Otherwise, it will refresh the data from the existing.
So, if you want to force it to prompt you for a new file, you have to move or rename the old file.
But, you're looking for the Pivot and Computed columns to refresh. Two things on that ...
Computed Columns: You don't have to re-import the file, if the rest of your data is current. Each column can be refreshed individually by right-click, Modify, then clicking Ok. You don't have to change any of the code; just hit okay instead of Cancel.
Pivot: In the menu, you have to set your pivot options appropriately to update when you Process (when the underlying data is Processed, really), or Manually (when you Process that section).
