how can I convert html to word
thanks.
I have created a Ruby html to word gem that should help you do just that. You can check it out at https://github.com/nickfrandsen/htmltoword - You simply pass it a html string and it will create a corresponding word docx file.
def show
respond_to do |format|
format.docx do
file = Htmltoword::Document.create params[:docx_html_source], "file_name.docx"
send_file file.path, :disposition => "attachment"
end
end
end
Hope you find it helpful.
I am not aware of any solution which does this, i.e. convert HTML to Word format. If you literally mean that, you will have to parse the HTML document first using something like Nokogiri. If you mean you want to output data persisted in your model objects, there is obviously no need to parse HTML! As far as outputting to Word, I'm afraid it looks as if you will have to directly interface with a running instance of Microsoft Word via OLE!
A quick google search for win32ole ruby word will get you started:

Good luck!
I agree with CodeJoust that it is better to generate a PDF. However, if you really need to generate a Word document then you can do the following:
If your server is a Windows machine, you can install Office in it and use ruby's OLE binding to generate the Word document into the public folder and then deliver the file in the response.
To use ruby's OLE binding, see the "Programming Ruby" ebook that comes with the one-click ruby installer for Windows. You may have to use custom logic to convert from HTML to Word unless you can find a function in the OLE api of Word to do that.

You could allow the user to download a PDF or a .html file, but there aren't any helpful ruby libraries to do that. You're better off generating a 'printable and downloadable' version, without much styling, and/or a pdf version using a library like prawn.
You could always generate a simple .rtf file, I think word'll be pretty happy reading that...

I was able to save the following in database
==heading===
Some __useful contents__ and **bold texts** here
I want to output ==heading== to <h1>heading</h1>
__useful contents__ to <i>useful contents</i>
**bold texts** to <b>bold texts</b>
Thanks
I'd recommend using Markdown for this purpose (same is used here, in SO).
You can get package that will convert markdown to HTML here in for C#. Or if you want client browser to render it (to save CPU on the server) you can use this JS plugin.
I have uploaded 1 PDF then convert it to xlsx file. I have tried different ways but not getting actual output.pdf2xls only displays single line format not whole file data. I want whole PDF file data to display on xlsx file.
i have one method convert PDF to xlsx but not display proper format.
def do_excel_to_pdf
#user=User.create!(pdf: params[:pdf])
#path_in = #user.pdf.path
temp1 = #user.pdf.path
#path_out = #user.pdf.path.slice(0..#user.pdf.path.rindex(/\//))
query = "libreoffice --headless --invisible --convert-to pdf " + #path_in + " --outdir " + #path_out
system(query)
file = #path_out+#user.pdf.original_filename.slice(0..#user.pdf.original_filename.rindex('.')-1)+".pdf"
send_file file, :type=>"application/msexcel", :x_sendfile=>true
end
if any one use please help me, any gem any script.
I would start with reading from the PDF, inserting the data in the XLSX is easy, if you have problems with that ask another question and specify which gem you use and what you tried for that part.
You use libreoffice to read the PDF but according to the FAQ your PDF needs to be hybrid, perhaps that is the problem.
As an alternative you could try to use some conversion tool for ebooks like the one in Calibre but I'm afraid you will lose too much formatting to recover the data you need.
All depends on how the data in your PDF is structured, if regular text without much formatting and positioning it can be as easy as using the gem pdf-reader
I used it in the past and my data had a lot of formatting - you would be surprised to know how complicated the PDF structure is - so I had to specify for each field at which location exactly which data had to be read, not for the faint of heart.
Here a simple example.
require 'pdf/reader' # gem install pdf-reader
reader = PDF::Reader.new("my.pdf")
reader.pages.each do |page|
# puts page.text
page.page_object.each do |e|
p e.first.contents
end
end

How can I insert an existing PDF into a Prawn generated document? I am generating a pdf for a bill (as a view), and that bill can have many attachments (png, jpg, or pdf). How can I insert/embed/include those external pdf attachments in my generated document? I've read the manual, looked over the source code, and searched online, but no luck so far.
The closest hint I've found is to use ImageMagick or something similar to convert the pdf to another format, but since I don't need to resize/manipulate the document, that seems wasteful. The old way to do it seems to be through templates, but my understanding is that the code for templating is unstable.
Does anyone know how to include PDF pages in a Prawn generated PDF? If Prawn won't do this, do you know of any supplementary gems that will? If someone can point me towards something like prawn-templates but more reliable, that would be awesome.
Edit: I am using prawnto and prawn to render PDF views in Rails 4.2.0 with Ruby 2.2.0.
Strategies that I've found but that seem inapplicable/too messy:
Create a jpg preview of a PDF on upload, include that in the generated document (downsides: no text selection/searching, expensive). This is currently my favorite option, but I don't like it.
prawn-templates (downside: unstable, unmaintained codebase; this is a business-critical application)
Merge PDFs through a gem like 'combine-pdf'–I can't figure out how to make this work for rendering a view with the external PDFs inserted at specific places (the generated pdf is a collection of bills, and I need them to follow the bill they're attached to)
You're right about the lack of existing documentation for this - I found only this issue from 2010 which uses the outdated methods you describe. I also found this SO answer which does not work now since Prawn dropped support for templates.
However, the good news is that there is a way to do what you want with Ruby! What you will be doing is merging the PDFs together, not "inserting" PDFs into the original PDF.
I would recommend this library, combine_pdf, to do so. The documentation is good, so doing what you want would be as simple as:
my_prawn_pdf = CombinePDF.new
my_prawn_pdf << CombinePDF.new("my_bill_pdf.pdf")
my_prawn_pdf << CombinePDF.new("attachment.pdf")
my_prawn_pdf.save "combined.pdf"
Edit
In response to your questions:
I'm using Prawn to render a pdf view in Rails, which means that I don't think I get that kind of post-processing
You do! If you look at the documentation for combine_pdf, you'll see that loading from memory is the fastest way to use the gem - the documentation even explicitly says that Prawn can be used as input.
I'm not just tacking the PDFs to the end: a bill attachment must directly follow the generated page(s) for a bill
The combine_pdf gem isn't just for adding pages on the end. As the documentation shows, you can cycle through a PDF adding pages when you want to, for example:
my_pdf # previously defined
new_pdf = CombinePDF.new
my_pdf.pages.each.do |page|
i += 1
new_pdf << my_pdf if i == bill_number # or however you want to handle this logic
end
new_pdf.save "new_pdf.pdf"
Is there any way to create a csv file using c#, which can have/show few values in Italic format, when we open it in excel.
Its just not possible. Theres no markup in csv. Either export an xls(x) or rethink your problem/solution. Why csv? It's not really meant for people to read. Only to transfer data from one application to another.
A CSV file is a text file where Excel can only interpret the type of field content as best (text, numeric, date) but not within a field. So the short answer is no.
There are libraries available for the ASP.NET MVC environment which allow you to create true Excel files so you then have complete control over field formats etc. A quick Google will find these.
UPDATE
A possible solution, if you are using MVC, is to create an HTML 'file' and then download that:
this.Response.AddHeader("Content-Disposition", "Employees.xls");
this.Response.ContentType = "application/vnd.ms-excel";
return this.Content(sb.ToString());
I've never tried this but have seen that it might work.
I have the rails application which accepts the XML output from another application. For some condition the XML tage content come up with CSS code
For example :
<\/sample/> .headermenu{float:left;no-repeat right;font-size:0.75em; padding-bottom:3px}, #div{float:left} This is the test value from another site <\/sample/>
In my ruby application i have parse the XML content and display the content.
It start displaying CSS content like the above. I want to display strip the CSS code if exist in the content.
Is their any way . we can do this please help...
raw method might help you.It outputs data without escaping a string. Check here http://apidock.com/rails/ActionView/Helpers/RawOutputHelper/raw for more details.
I dont know if this is what you are looking for but you can try css parser by the way whenever you need a rails or ruby gem just search for it at rubygems
