["Manoj Karthick (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-10297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17270671#comment-17270671 ] 

Manoj Karthick commented on ARROW-10297:
----------------------------------------

[~jhorstmann] - This feature would be very much useful for me as well. Would it be okay if I worked on this based off your changes on [PR #8686|https://github.com/apache/arrow/pull/8686] and incorporated the comments in that PR?

> When analyzing data related issues I found it really helpful to filter or portprocess the contents of parquet files on the command line using jq (https://stedolan.github.io/jq/manual/).
> Currently the output of parquet-read is in a custom json-like format, I propose to add an optional flag that outputs the contents as json using the serde_json library. This should probably be behind a feature gate to avoid adding the dependency for everyone.
