I am a complete newbie when it comes to web page design, and what I am trying to achieve is a web page that I can display on a wall mounted screen as an office dashboard. I have data in excel that is constantly being updated (on the server) and I want to be able summarise this and display it (e.g. total orders etc.) for staff to see. Therefore the web page needs to be able to connect to the data source, and update itself every few minutes. I am hoping to then use Ubuntu or even Raspberry Pi to drive the dashboards.
Can anybody point me towards either some clear instruction on how to achieve this, or better still some sample files that will help me see how its done?
Really appreciate any help!!
If you want to use PHP, you can use PHPExcel, to read your Excel files, and if you want to only display the information as is, you may output it to HTML directly, there is an API to manipulate the Excel file, so you may use that to summarize your data, however, if you need something cleaner, you may want to use Windows instead of Linux, given that in Windows, you can use an Excel file as a data source, and there are third party products that can use them as if it were a database (using SQL queries to retrieve data).

I work for a small publishing company with an internal website that displays a static HTML table of our published products.
We have a need to be able to list and sort published products (about 1-2 items are published per day) dynamically that is being fed from an Excel spreadsheet. The Excel spreadsheet is what we are currently using to maintain the data. The Excel spreadsheet is on a shared network drive available to the company.
I am familiar with AngularJS, ReactJS, and VueJS2 for front-end development and was wondering if I would be able to use one of those tools to consume a Excel file, parse it to JSON, and then display it dynamically on the client side.
Is something like this is possible?
When a user finishes editing the Excel sheet and saves it to the shared network drive, is there a script that would automatically save the data as JSON? I assume we would then simply have our Javascript framework reference and consume the saved JSON to populate its published products list.
Note: We are unable to use a relational database at this time (ie MySQL).
Part 1 - generating json from excel...
front-end technologies are not the way to go. You need to run a service that watches folder for change (like nodejs or python). Saving as csv instead of xls might make things easier as you may not need extra libraries to make sense of your xls file
Part 2, displaying json data...
Your browser, by default, cannot load a local json file. So you may need to run a server (again nodejs and python make this relatively easy) to host your json file.
there are many ways of presenting data these days, but without knowing some of your particular and based on the information you did share, looks like you've got a steep learning curve to get something like this going.
I have a site that I'm looking to transfer to Volusion. Importing tabled content into Volusion's a breeze, it's getting it tabled that's an issue. The old site has no real ability to export, nor do I know how to get at it's database. I'm thinking there must be some sort of script I can write to take the content from the frontend and download it in some sort of list that I can put into a CSV, and put into Volusion.

Any suggestions? I'm hoping to get in the image directory as well and download all them for upload to the new site.
You are going to need at the very least a file with product code, product name, weight and price.
Looking at the URL you provided it doesn't appear that the products their follow any type of orderly structure where you can target the images folder or products based on a known piece of information like a products code. Unless the back-end has some type of product export function you may have no choice but to recreate it from scratch.
I don't know if you solved this yet or not, but I would suggest scraping the data providing you have the information on the old site currently. This can be done easily using vbscript and excel, or if you aren't very savvy at coding you could look at a piece of software called mozenda. There are a whole variety of methods that can be used to scrape data, all of them pretty easy to learn with a bit of research. Basically you write a script that will crawl your dom and extract the data (to xml works best in my experience)
Hope this helps.
Does anyone have an elegant suggestion for how to get the contents of an Excel spreadsheet into SQL Server via a web form? I need to allow our clients to upload modest amounts of structured data, and I need that data to ultimately reside in a sql table. I really can't expect the clientele to produce anything but an Excel file, but I could require that it be an xlsx.
The web app is written in Coldfusion; it doesn't need to be able to handle huge numbers of simultaneous requests, but I don't want to consider some sort of server-side batch job processing or shunt the user to an asp.net page (which is what we are doing now).
Any recommendations (or examples of how others are successfully doing this) would be appreciated. Due to the sensitivity of the data, we really can't do anything to compromise the security of the web or sql servers.
If you are using CF9, then you could easily use the cfspreadsheet tag too. I mention this one specifically because Shawn's link did not (presumably due to its being relatively new on the CF scene). Here's the livedoc link: http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec17cba-7f87.html
For full use, I would create a web form with a standard file upload field. On the backend handling the form submission, get a copy of the file with
<cffile action="upload" destination="uploaded.xls".....>
Then use:
<cfspreadsheet action="read" query="myExcelData" src="uploaded.xls" ...>
At which point, your spreadsheet content will be available as a query object. You can then loop over this query, running insert queries into your sql server each time you loop. That should do it.
Here are the most notable options to help point you in the right direction; choose what you are most comfortable with (Source: Charlie Arehart).
CFXL
JXLS
CFX_Excel
My personal recommendation is to go the CFX_Excel route. Although a commercial product, it will grant you the most functionality/flexibility of the options listed.
I am currently working on completing my Masters Thesis project. In order to do so I need to be able to obtain the raw data accumulated in NagiosXI and/or OPSview. Because both of these are based off of the Nagios core, I assume the method to obtaining the raw data may be similar. This raw data is needed so that I can at a later time perform specific statical calculations which relate to my Masters Thesis. I have looked online and so far found some Nagios plugins which obtain raw data and then manipulate it for graphs and visuals, but I need the raw numbers in order to complete my calculations.
I am also researching to see if I can create maybe a PHP script, or some other language, that will extract the data from Nagios and save it in a word or excel document. However, this would be a bit of extra work as I am unfamiliar with either PHP or MySQL queries. Because of this I hope to be able to find a plugin, or something similar, that can get the data for me.
Cyanide,
I can't speak for NagiosXI, but I can for Opsview :)
You could access the data that is stored in the RRD files. You can use rrdtool dump to pull the values out or use a URL like: /rrdfetch?start=1307608993&end=1307695393&hsm=opsview%3A%3ACheck%20Loadavg%3A%3Aload1&hsm=opsview%3A%3ACheck%20Loadavg%3A%3Aload5
And this returns back the JSON data points. This is undocumented, but is used to power the interactive javascript graphing.
Alternatively, if you have ODW enabled with full statistics, then the raw data is stored in the ODW database and you can then extract the raw data with SQL commands. See http://docs.opsview.com/doku.php?id=opsview-community:odw for more information.

You can try use mk livestatus http://mathias-kettner.de/checkmk_livestatus.html
or http://exchange.nagios.org/directory/Addons/APIs/JSON/Nagios2JSON/details
All this tools get you status data without need to go to DB or status file. While XI is based on Nagios it can still work with him.
Please take a look at http://dmytro.github.com/nagira
It's a web services API to access Nagios data. You can get all hosts, service status data, objects configuration in multiple formats JSON, XML or YAML.
background
I need to be able to display charts that can capture what the user has clicked on. So for a pie chart, if a user clicks on a pie piece, I should be able to capture which piece he selected. Scatter plot should capture what plot, etc. Access-UI can't capture these things, only that a user clicked on the graph. So I need a different solution.
problem
We do not have access to a web server. The front end needs to connect directly with the access database. So what front end solutions can I use that will give me the UI flexibility I need to solve my problem?
possible solutions?
Use silverlight in access (http://desktopweb.blogspot.com/2010/12/using-silverlight-with-access-part-ii.html)
Winforms that connects to Access database via ADO
Is there anything that allows me to use HTML/JS or flash? HTML/JS would be the best solution, followed by flash just due to its wide support. I was researching Web Browser Control but I am not completely clear on whether it is opening local HTML files or browsing through http. I also wasn't clear if it supports JS or can load Flash.
When you first said about the click though capability my first thought was the reporting that is possible using SSRS. The easiest way is to have a reporting server and have the reports available through a browser. However you say you can’t have a web server so I’m guessing that a reporting server is also out.
You could however still use BIDS or report builder to make your reports and then the report viewer control in a flavour of .net to display the reports. Note that you have to convert them to RDLC files and feed the data to them.
That’s my 2p worth, I won’t comment on flash or silverlight as I don’t know enough about them to make an informed recommendation
The web browser control that's usable in Access can use any resource that can be reached via a URL, or you can assign a string of HTML (valid, of course) to it. I forget the exact property you use for the latter, but it's doable (I didn't know this the last time I implemented a web browser control to display HTML from an Access app, so created a temp file, and never went back to replace that with just assigning the HTML directly once I learned how -- so I forgot how, of course!).
