Converting Currency Values in Numbers (#1532)

 Converting Currency Values in Numbers (#1532)


There are a lot of different ways to convert currency values in Numbers. Let's take a look at some of the functions. I'm going to start a Formula here by hitting the Equals key. On the right I'm going to search in functions for things that have to do with currency. So let me search for currency. You can see that there are four different functions here. So let's jump ahead and take a look at Currencyconvert which is a really simple one. So we look at the function here and it's currencyconvert value into currency-code. We can start with that. We'll convert say if I want to convert ten dollars. Since I'm set to be US English for the language it's going to assume dollars. So ten but I'm going to convert to Euros. I'm going to use the currency code for euro, EUR, as a string inside quotes. I'm going to get a result there. Now another thing I could have done is I could have provided a string here with a currency value in it.

So 10 with the dollar sign, $, and it would work. That's one way to deal with making sure that you're in the right currency. Use a string instead of a number. If I was actually going to use something like $1in here and it's formatted as dollars then it would pick it up and make sure it uses the right currency. So I'll do currencyconvert. I'll select this cell as the value and I'll use the euro as the code. So that's a pretty simple way to do it. It's going to take the number from the previous days' close. So it's not a live currency update but it's close enough. It's just what it was at the end of yesterday. So for exact calculations you may want to have some more sophisticated financial software. But for just general things with what today's price is, this will work. Now let's take a look at some of the other functions. So we'll delete this formula here and we'll look at Currency. So Currency what it will do is it will convert from one currency to another and give you the price.

So, for instance, I can do Currency and I can say US dollars to euro and what it will give me is basically how much one dollar is in euros. I can put another parameter here and you can see there's a list of them. There's change, percent change, open, high, low, 52 week high, etc., etc. So I could basically go with say the open price from yesterday and it will give me that.

So you have some more functionality there. Now there are also some other ones here. CurrencyH which is historical. So not only can you get a lot of that same data for the current day but you can also set a date. So you can go, say, what was it the end of last week or a year ago. That kind of thing. There's also a currencycode function which will tell you the code for value. So if I were to do, let's say, currencycode select this which is know is a dollar amount I'm going to see that it is in US dollars. If this was in euros then it would put EUR. Now how about these codes. How do you figure out what they are. So you can see here in the description for all these functions that it says that the currency codes are defined by ISO 4217. So if we simply search for ISO 4217 we can find that in Wikipedia and quickly get to the table here where it tells you codes for different countries and currencies.

Download Historical Exchange Rates into Excel with a Click

 Download Historical Exchange Rates into Excel with a Click



Hey guys, this is Yi from ExcelClout.com with another Excel tool to share with you. This time I'm going to show you a tool I've put together that can automatically download historical exchange rates right into Excel. And with this tool, you can download your historical currency data with a click of a button. So here we go. This is the url where you can download that file, or you can get there by Googling Excel Clout (C-L-O-U-T) historical exchange rates. And it should be the first link in the search result. Let's click on download and open the file. Now because the file was downloaded from the Internet, the first time you open this file, you may get this security warning. We need to click on enable editing. And the file contains macros. We need to enable the macros by clicking enable content. And it's important that you enable the macros because it's the macros that's going to automatically download your foreign exchange rate data. This Excel file basically comes with a form as you see here. And all you have to do is fill out this form, and the macros will take care of downloading the currency data you specified.

Over here, you have a currency codes reference table in case you need look up any currency code. Now I am going to show you how quick and easy it is to get your historical foreign exchange rates, so you can focus more on your historical analysis instead of searching for data. First, we need to specify the currency pairs we'd like to download. For example, let's change the currency pairs over here to, say, EUR/USD for Euro vs U.S. Dollar, USD/CAD for U.S. Dollar vs Canadian Dollar. Make sure you have that slash in between the currency pair so that the macros can recognize the currency pair you've chosen. Just enter the currency pairs in a list like this. Next let's set the From date to, say, 8/1/2000, and the To date to 8/1/2010, so that the spreadsheet will automatically download 10 years worth of historical currency data.

And last you have the option to set the frequency of your data. If you set the frequency to daily, you're going to get the exchange rate for each weekday. Weekly would give you the exchange rate on the last day at the end of each week. So you'll get the exchange rate on the last day at the end of each selected period. You have other options such as monthly, quarterly, and yearly. Normally we'd keep the frequency at daily so we get all the historical exchange rates for every weekday. So now we're ready to click this Download Data to New Sheet button, which is the centerpiece of this tool. When you click this button, what's going to happen is the specified historical exchange rate data will be automatically be downloaded and organized into a new sheet within this file. If you look over here, you have two sheets in this file right now: the Form and Sheet1. As soon as you click on this download button, a new sheet with the automatically downloaded exchange rate data will be added. So let's click on the download button and send the macros to work.

And you see that a new sheet called Sheet2 has been added. Let's go to Sheet2 and check out the currency data we just downloaded. We have the dates in one column and the historical exchange rates for each currency pair in separate columns. Now a quick note about the data. The foreign exchange rate data is downloaded from Quandl.com (Q-U-A-N-D-L). Quandl is like the Wikipedia for financial data.

The currency data is pulled from one of Quandl's currency data sets that covers a boarder set of currency pairs, even including some that are not traded in the foreign exchange market. However there's a catch. In an email exchange with Quandl's CEO, I found out that there is no timestamp for the data, which means we don't know what time the currency rates were recorded.

That's because these daily rates are derived from multiple sources such as exchanges, brokerages, and central banks. Despite the lack of a timestamp, the historical currency rates can be used to spot trends or large movements. And Quandl offers unlimited access, so you can download as much data as you need right from this file. In very rare occasions, Quandl could be unavailable possibly due to maintenance. And in this case, just try downloading your data again at another time.

So now you have this handy tool to download your data, and my recommendation is that use this tool just to get your data. Once your data is downloaded, like we have over here, move the data to another file for your final analysis. And that's it! I hope you guys find this Excel tool useful.

ROUGH TRADE -s/t EP 1980

One more awesome punk band I can present you here is Rough Trade from Ă…lesund, Norway. They released this pretty self produced EP in 1980 and have been featured on compilations such Anarki & Kaos: Norsk Punk Vol.1 and Bloodstains Across Norway (coming soon). And if you like early scandinavian KBD sound then you will love this record. One side sung in native norwegian while the flip is held in english. Six numbers and they all have that dirty garage touch as I love it. The guys can play their instruments and what I like in particular is their flexibility. Fast Hardcore, Ska-elements and groovy '77 style crackers and even a live recording on this plate. Wow!! - Unfortunately track #3 is missing and should someone have it please send them. In 1994 the label Intense Heartbeat Records released a CD called Du Er En Dritt with all their recordings (twenty-one songs) and I will hear this, so feel free to drop me a mail. End of story!

- Extra Thx to Fredrik -
