+The basic usage is to export a text or range of texts in `tsv`. The data can then be viewed or manipulated in the spreadsheet, and the result imported back into `bilara-data`. 
 
 A typical use case would be if we discover that a text has an extra unwanted segment break, we can combine two segments into one, delete the old segment, and re-import it. Changing this in the raw json files is tricky, as you have to keep track of all the different files of that particular text, and re-increment the segment numbering.
 
-Bilara i/o uses [Pyexcel](http://www.pyexcel.org/) under the hood, so data can be imported and exported to [any format supported by pyexcel](http://docs.pyexcel.org/en/latest/design.html#data-format). However we have only extensively tested it with `.ods` spreadsheets.
