openlp.org Bible Database Creator allows you to create openlp.org bibles from CSV files. Then all you need to do is to put the file you generated into the <openlp.org folder>\data\bibles folder, and openlp.org will pick it up automatically.
The format of the CSV file is as follows:
[book],[chapter],[verse],"[verse text]"
