un-xtab 1.0.0

Un-crosstab data in a text file.

un-xtab.py is a Python module and command-line program that rearranges data from a crosstabulated format to a normalized format. It takes data in this form:

Station	2006-05-23	2006-06-15	2006-07-19
WQ-01	4.5	3.7	6.8
WQ-02	9.7	5.1	7.2
WQ-03	10	6.1	8.8

and rearranges it into this form:

Station	Date	Value
WQ-01	2006-05-23	4.5
WQ-02	2006-05-23	3.7
WQ-03	2006-05-23	6.8
WQ-01	2006-06-15	9.7
WQ-02	2006-05-15	5.1
WQ-03	2006-06-15	7.2
WQ-01	2006-07-19	10
WQ-02	2006-07-19	6.1
WQ-03	2006-07-19	8.8

Input and output are both text (CSV) files.

You can use the un-xtab program to rearrange data that have been provided in a format designed for readability into a format that is more suitable for storage in a database, or for use with statistical, modeling, graphics, or other software.

The un-xtab program can deal with crosstabbed formats that include multiple rows of column headers and groups of data values that were crosstabbed together.

A row number can be added to assist with post-processing of the output file, if necessary.
