Monarch was originally developed by Math Strategies for Personics Corporation.
The software is published by Datawatch Corporation, which was acquired by Altair Engineering in 2018.
Monarch allows users to re-use information from existing computer reports, such as text, PDF and HTML files.
Users define models that describe the layout of data in the report file, and the software parses the data into a tabular format.
The data can be exported to a variety of formats, primarily spreadsheets.
