What does it do?
Do you often have a need to display currency conversions in your Google Workspace emails, Docs, Sheets, Slides or Calendar?
Are you a little annoyed that you have to head over to an external site or jump onto Google each time to make a conversion – copy it – head back – and then paste it into your document?
Currency Converter seeks to solve this problem by providing a currency conversion right inside your Google Workspace environment. It is hoped that Currency Converter will help you to recapture some much-needed time in your busy work life.
Currency Converter allows you to convert currencies based on daily exchange rates right in your Google Workspace sidebar. You can even modify the currency conversion to your own preference or region.
How does it work?
Currency Converter is simple and easy to use.
After you have installed the free add-on from Google Marketplace, simply click the icon on the right sidebar and accept the non-intrusive authorisations.
- Select your currency from
- The amount you want to convert
- The currency you want to convert to.
- Hit Submit
Your conversion will appear below for you to select and copy and paste into your Google Document, Gmail, Sheet, Slide or Calendar details.
Why doesn’t the conversion result just automatically load into my document?
I definitely could have created that functionality, but this would require greater scope and edit access to your documents. I wanted to have the least amount of scopes and access possible for your peace of mind and privacy. And really a quick-select and copy and paste is not a lot of work.
Want a different format of the conversion? Want to save your preferences?
I’ve got you covered.
Customizing your currency conversion results.
You can change how you want your currency conversion results to be displayed by accessing the advanced options.
Just before the Submit button, you might have noticed the little down arrow or
'v'. Click on that to expand the options.
This will reveal the advanced options. You can:
- Change the display pattern.
- Choose to add the currency symbol or not.
- Choose the locale format (Some countries use commas and periods differently to separate numbers or identify decimal numbers).
You can also save all these input values as default for the next time you need to use Currency Converter.
Where does the currency data come from?
Currently, the currency data is extracted directly from the European Central Bank. The European Central Bank updates its latest conversion rates daily around 4 pm CET and Currency Converter tries to capture this update as soon as it appears.
