Update: The beta test is over, the feature is launched.
We’re launched our new data upload page, which introduces three exciting new ways to get your data into Datawrapper.
In addition to the current options (copy & paste and CSV upload), you can now
- upload Excel & LibreOffice files directly
- connect Datawrapper charts to link-shared Google Sheets
- link Datawrapper charts to a CSV-file so that your chart will update automatically when the data changes.
1. Uploading Excel & LibreOffice spreadsheets
Until now you could only upload CSV text files, but thanks to the amazing Sheet.js library, Datawrapper can now import your Excel / OpenOffice / LibreOffice spreadsheets as well (basically every file with the extensions XLSX, XLS, ODS, CSV, TSV, TXT or DBF). If the document contains multiple sheets, you will be asked to select the one you want to import.
Note that we’re still only storing the one sheet you chose to import. So if you want to access the other sheets later, you’ll need to upload the file again.
2. Connecting to Google Sheets
In case you’re already working with Google Sheets you may be pleased to hear that you now can connect them with Datawrapper directly. To do so, you need to make sure that Link Sharing is activated for the document and then paste the Google Sheet URL into Datawrapper.
Datawrapper updates your data from your Google Sheet every time you open the chart or reload the site. You don’t need to worry that all your published charts suddenly update every time you make changes to your Google Sheet: You need to publish your chart again before the new data becomes visible.
3. Linking external CSV files
Sometimes, you do want a chart to update as soon as the data updates, for example in an election. We now offer a way to do so. Even in published charts the data will be kept up to date. That means that for every chart view, the data will be downloaded freshly from the original URL.
This can be a bit tricky, technology-wise. To make it easier, we take care of the complicated stuff for you. We decided to throw in a free data hosting service. Meaning, you just upload the CSV to e.g. your website, Github, or even Google Sheets (we explain you how in this Academy article). From there we copy it to our own server in certain intervals (every minute on the first day, then every hour the next 29 days), and your Datawrapper chart will pull the data from there:
If you don’t sweat about all these technical terms (HTTPS, CORS, and high traffic) and want to have full control; or if you need a higher update frequency, we still offer you the complicated way:
We hope that you find these changes helpful. Please do let us know if you have some feedback, via email or in the comments below!
In case you’re wondering why we aren’t just asking our users to connect Datawrapper to their Google Drive account, instead of having to enable link sharing for each document individually – here’s the answer:
When you connect a third-party application to your Drive, you’re automatically granting access to all documents you ever stored in it, even if you only wanted to import a single sheet. While this might have been the more convenient option we ultimately decided in favor of protecting our users’ privacy. ↩
Here’s the trickiness: The chart pulls the data from the CSV file that needs to be on a server that supports CORS (cross-origin resource sharing – so that Datawrapper has access to pull data from this server), has HTTPS enabled, and needs to be ready to handle high loads (because the data will be pulled from the server every single time a reader views your chart). ↩
