|Getting data from Internet into Excel
Tuesday, November 01, 2011 - Office for Mere Mortals
Ever seen some data on the Internet and want to copy it for yourself? From small tables to large data chunks, there’s several ways to do it.
Almost any table or grid on a web page can be copied into Excel with the web page cells becoming cells in Excel.
For example this, admittedly self-promoting, table:
Simply select the entire table with your mouse pointer. It doesn’t matter if you include some text before and after the table; you can remove the excess later.
Then paste the web table into a blank Excel worksheet. Here’s the result with the sentence before the table included.
This method only copies displayed data, not any formulas. The last column ‘discount’ could be calculated but no formulas are copied, only the displayed values.
As you can see, all the web table data is now in Excel cells. The hyperlinks from the table have been preserved as well as the formatting. But it needs a little work to make it useable.
The top row can be deleted to put the table headings in row A.
Column B is too narrow (that’s why the #### marks appear) widen until the numbers show up.
Widen the other columns so the headings don’t wrap in such an unsightly way.
Tip: to automatically adjust a column to fit the contents, put the mouse pointer on the divider between column headings until you get the twin-arrow icon then double-click. A similar trick works for rows.
Choose Data | Filter to make the column headings into data labels which you can pull-down on to filter or sort upon.
Notice that Excel has been smart about the currency values. The $ sign has been stripped out of the web table text and the cell automatically changed to a currency value with $ prefix in the formatting.
It’s best to check that Excel has done this, especially with other, non dollar, currency signs.
Not only are the numbers imported as the displayed values only (as opposed to higher precision underlying values in an Excel worksheet) but they are imported as text – it’s up to Excel to figure out what the cell values are and change them accordingly. It can cope with currency and numbers as we’ve seen. Dates are usually converted too, but that depends on the formatting of the text values.
You can use Excel formatting commands to change the look of the data from whatever was on the web page. The formatting you get depends, in part, on which browser you copy from. No surprise that the most consistent results come from using Microsoft’s Internet Explorer.
Doctor Who and the curse of the evil worksheets
There are plenty of publically available worksheets available. Google Docs online spreadsheet application encourages people to make worksheets public. They make is easy to do in a way that Microsoft does not.
Some of the data is serious and important but other worksheets are more quirky. For example this worksheet of all the villains and monsters from the long running UK series, Doctor Who courtesy of The Guardian.
The entire list is available from Google docs here.
You can select cells or the entire list and paste into Excel, as described above. However that’s clumsy for a large worksheet and doesn’t include any cell formulas.
The easier method is to download the whole worksheet. In Google Docs you can do that from the File | Download | Excel menu,
Then you can open the XLS file in Excel and format to your heart’s content.
Downloading a worksheet should also include any formulas.
Not all public data is so frivolous. Data.gov is a web site full of data sets from the US government.
Many are available as Excel XLS downloads, like these details of oil and gas production.
This is very raw data – over 37,000 rows of information and cryptic headings like “conden_prod_BBL”.
There are explanatory documents linked from the download page.
The Guardian Datablog
The Guardian newspaper in the UK has an interesting blog about data sources and presenting them in interesting ways.
For example a visualization of the cause of death in the UK which includes near the bottom, a link to a worksheet with all the raw data. Readers are welcome to download the data for themselves.
The World Bank
Another data source is The World Bank where you can download Excel worksheets compressed into ZIP files for faster downloading.
