tWriteJSONField quotes numeric fields

Anonymous — Thu, 06 Apr 2017 17:08:03 GMT

Dear folks,

it seems the component tWriteJSONField doesn't respect the data types of incoming columns and just writes all values in Strings.
My expectation is, that numeric values are not enclosed in quotes in the output of the component.

This causes me big trouble in a use-case, where I have to transform an Excel file with several columns to a JSON String, since the numeric values are all quoted and thus the application parsing the file fails...

I'm working with TOS 6.2.1.20160704_1411.

Are there any known workarounds?

Example Job:
JSON_EXAMPLE.zip.zip

According to the documentation: https://help.talend.com/search/all?query=tWriteJSONField
...the default type of all elements is String. If you want an element to be numeric, you need to add an attribute named "type" and give it the static value of the type you want.

Hi cterenzi,

thanks for your reply, this actually works fine.

However, if you have > 200 columns where you have to define the type like this, this can be a tough job ^^ But I guess there is no other possibility right now *lookingforthetrainee*.
