Converting JSON output to csv

[Alla Kennedy]

Is there a way to get data from REST API in a csv format instead of JSON without additional converters?

Raw JASON comes with a lot of extra data, we are having problems flattening it.

Need to GET a list of issues.

I need to create a batch job that sends updates from JIRA to an external database. The only way I see it is through REST.

Looking into PowerShell now and Invoke-RestMethod looks promising. Are there any good sources for JIRA REST code in PowerShell? All REST tutorials seem to be in old command-line curl.

Sorry, that should have been a Reply to Nic, not a separate Answer..

I don't know, I've not used PowerShell since I gave up on Window many many years ago.

The xml and csv should still work though, they come over plain http(s) with no formatting.

So is it possible to grab JIRA data in plain xml and csv automatically, without going to JIRA and exporting it manually?

[Nic Brough -Adaptavist-]

Yes, just hit the url the issue navigator links to for an xml or csv export.

I apologize if I am not expressing myself clearly. Manual CVS export from Jira is not suitable for our needs. I need to create an issue list programmatically, so I can:

1-run it automatically as a batch, e.g. through the scheduler;

2-have more control over columns selection , ordering, data formatting, data display etc. I am facing many, many problems with the data exported manually through Jira's Export facility. Data that I get through REST seems more accurate, but I have to deal with JSON.

I don't understand?  If you can hit a REST url, you can fetch an http one the same way.

The data you get from REST is just as "accurate" as what you get from CSV or xml links, it's just a different format (although I'd say JSON and xml are better representations than xml)

[Nic Brough -Adaptavist-]

No, it's JSON only.

One of the reasons REST throws out JSON is that CSV is generally too simple to represent some of the data usefully.  I suspect the problem you're having "flattening JSON" is because the data simply doesn't fit into a CSV layout.

However, you don't have to use REST - you could also hit the urls in the issue navigator that provide the results of filters as xml or csv.  Run a search and look for the export options
