Customers use web queries to grab data in the tables directly from our website and place them into excel where they can automatically work on it. while trying to grab data from our website, we noticed that table markers were not shown. excel is unable to recognize the tables on the web page.
Website was developed using RoR.
can someone help us with this issue?
You may want to consider using Power Query instead of regular web queries. With the "from Web" option you can get the DOM into Power Query and access any DOM element.

I have a google form that is being used by the employees of my firm to upload stock details. Now daily it has around 20 entries daily. I used google form since I can manage the data in google sheet pretty easily. But using IMPORTRANGE on these files has made it very slow. Thus, I wanted to shift to SQL database.
The issue I am facing is that if I push data from google sheet, then I'll manually have to do it everytime. I want that google form to send the data to the sql database directly so that I can manage the data on that which can increase the computational speed.
PLEASE HELP!!!
Currently I am using google sheet to manage the data, which is very slow.
I'm developing an application on Rails and MongoDB which imports CSVs with hundreds of thousands of records and draw graphs and charts on that data. I have a MongoDB collection of 800K documents, which I wanted to render fully to the front-end and then process the data on the front-end through JS. But the browser hanged while receiving the response.
I'm not sure whether this is the right approach or not. Should the data be streamed to the browser or it's not a good idea to send 800K documents to the browser? If not, I can filter the data on the backend and send the filtered data to the browser.
Looking forward to expert suggestions.
You need to use datatables (https://datatables.net/) this will filter and call 10 - 100 records to process on the browser and that is will solve your issue :)
also for the charts you need to filter the selected data to show on your view :)
I'm looking at visualization options for a graph database project that I have coming up. Part of the job is to provide an interactive visualization of the data for public website visitors.
The standard Neo4j Server Web Interface does all I would need it to and more. I was wandering if I could simply embed it in a webpage or provide a public url (that could be accessed without a login) that general users could use to view the visualization without being able to edit it or add nodes/relationships? If you know of any examples of how this can be done, I would be very grateful.
Thanks!
The Neo4j browser is an Angular.js application using d3.js as visualization. The code is all open source an on https://github.com/neo4j/neo4j/tree/2.2/community/browser/lib/visualization so you can check it out there.
In general http://maxdemarzi.com is a good source for visualization blog posts as is http://neo4j.org/develop/visualization
Check out Neo4j GraphGists. A GraphGist allows you to embed a Neo4j database, Cypher queries, and visualize the results in a web page. Lots of examples listed on the GraphGist wiki.
Also take a look at Mashed Datatoes, a bar chart, pie chart like visualization software for Neo4j.
It uses Movie database for demo. Try selecting "Person" as start label.
I have website and added the google custom site search. It works fine and displays the results. The pages are stored in the database and allowed to edit by Administrator (as CMS solution)... How google search the content and displays from my database content? I would like to know the technique or method google follow?
Google does not have access to your database, only your web pages. It regularly crawls your web pages and indexes them, just like it would for its own search results. The only difference is it serves up results specific to your website to your website.
A company is creating a web site for the organization I work for. Since the web site is still being developed, some modules are not yet there. For instance, in order to print data obtained from a query, one needs first to export it to Excel or Access. Then, from Excel or Access, it is important to do some adjustments (adjust columns width and rows height, modify titles, so on) to make it easy to print.
I would like to create a small web application that will avoid us doing those operations manually. Unfortunately, the other application is in JSP/Java while I only know ASP.NET/C#.
How can I retrieve all this data, which are either in Excel or Access, and reload them into my application for printing?
Thank you
This guy did a brilliant article on getting data from excel using ado.net, I have written a program based on his instructions and it is working fine with Excel 2007 files, and can handle very long column data as well.

Have you considered writing a macro in Excel instead of trying to do everything on the server? Creating a macro in VBA isn't difficult, and you can distribute it as an Add-In to your users. Takes some good instructions for them to install it, but avoids all the potentially messy issues of import/export of Excel files.
