Comma Separated Values Data
< BACK TO DATA SOURCES
Corda Server can import data from comma separated values (CSV) files. This is a common format that can be viewed and edited
in many spreadsheet programs. Comma separated value files are files where each data value is separated by a comma,
and each row of data is placed on a new line.
For example, there are example comma separated value files in the examples/data folder of the Corda Server document root
directory. You could import the file data1.csv into a graph using the Corda Embedder loadData()
command, as shown below:
myImage.loadData("graph","examples/data/data1.csv");
Or, you could import data from the example uspop.csv file using the Corda Embedder loadMapData()
command, as shown below:
myImage.loadMapData("US","Areas","examples/data/uspop.csv");
CSV data can also be imported from URLs, meaning that you can have a web application generate
your CSV data on the fly. For example:
myImage.loadData("graph","http://myserver.com/getdata?mon=Jan");
