![]() In particular, we will use two functions to retrieve real-time weather information from. Turns out Excel offers some built-in tools for utilizing this functionality. Here’s an in-depth introduction to XML, but almost everything you need to know is in the name: Extensible Markup Language.įrom Wikipedia: Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.Īs we will see in the example, XML provides a set of rules for reading and writing information onto a website. Here, for example, is the insides of the weather report in Akron, Ohio: URL: If you’re running Chrome, you can peek into the code of any web page using Ctrl + U. It’s crazy to think that even the most artistic websites (mine included, of course) are built on code. Be sure to subscribe to my channel for more Excel tips. Data source: Looking to automate daily historical weather data collection? Check out this post. In this lesson we will get real-time updates from. XML data straight from the web into Excel with the WEBSERVICE( ) and FILTERXML( ) functions. I suspect the time to process will drop.Requires Excel 2013 or greater. Next week I will have a 2017 iMac 27-inch with a 3.5 GHz processor and 512 GB SSD. It takes around 12 to 14 seconds to import a month of data on a Mid 2010 iMac 27-inch with a 2.93 GHz processor and a Hard Disk Drive. The first 90% of software development takes 90% of the time. I hope to be finished this week but problems can always occur. So, if someone wants to use the program I would have to have examples of their data files to ensure that the conversion is done correctly. I don't know if users with different sensors (solar, uv, soil temperature) have a different file format than I do. I have not put in the code to do this as all my data is metric so I don't have test data for other formats. So, the program would have to know the units that the user specified and do the conversion. It appears that WeatherCat always stores the metric data and if required converts it to the format the user wishes to display. Someone may have temperature in Fahrenheit but pressure in mb rather than inches. So, for example, I use all metric units but some people may use all English units or a mixture of both. There is also some error handling that needs to be done.Īlso, it appears that Weather Display stores data in the units that the user specifies. Write the interface code so that a person can put in the input directory (where the Weather Display files are located) and the output directory (where the X_WeatherCatData.cat should be placed.) put all 2012 files in a directory called 2012. That is a structure which puts each year's files in the appropriate directory names for the year. Write code to go through all the files and export them into the proper directory structure. I can search and get all related files from Weather Display. It looks exactly like the WeatherCat data file that WeatherCat produces but I have not yet tested it by moving it into the WeatherCat directory. Import WeatherDisplay data for a month into a M_WeatherCatData.cat file. I think they may be System status codes but I do not know what they are. There are keys in the X_WeatherCatData.cat file that I do not understand. Correct? Do I need to put this in? If so, what is it?ĩ. This is just a line number and has no significance. The first entry in each line of a X_WeatherCatData.cat file is a number. The line separators in the X_WeatherCatData.cat files are /n. Correct? I will put them in but I was just curious.ħ. The headers in the X_WeatherCatData.cat files are optional as the important data is in the key:value pairs. The data in the X_WeatherCatData.cat files is in UTF8 (plain text). This will bring all my historical data into WeatherCat. Upon starting WeatherCat will create a new X_ file for ALL of the new X_WeatherCatData.cat files. If I change a file I must delete the X_ file? Correct?Ĥ. In each directory the files are named X_WeatherCatData.cat with the X being 1.12. ![]() I would need to create the proper directory structure with a separate directory for each year. I would like to confirm a few things before I do this. I know enough Swift/XCode that I can write a program to extract the data from Weather Display files and put it into. I have looked at the documentation and format of the 6_WeatherCatData.cat file. I have data from August 2008 to today in Weather Display files.
