Combine two JSON Arrays to one

(1) Share

Posted on by u4jaanus

Hi,

Running parallel flows, doing fetch data from different sources, result is in same format which is JSON Array, I also had it in String format.

Tried Join (found out its totally different thing), then used concat and end up having two arrays in one JSON object.

Any way to combine two arrays into one JSON array please?

Two Arrays.

[
 {
 "productcode":"IRECP",
 "FreeStock":"5",
 "ExpectedStock":""
 },
 {
 "productcode":"N10001",
 "FreeStock":"0",
 "ExpectedStock":""
 }
]

[
 {
 "productcode":"EK20",
 "FreeStock":"1.00",
 "ExpectedStock":"20.00"
 },
 {
 "productcode":"EL50",
 "FreeStock":"-8.00",
 "ExpectedStock":"299.00"
 }
]

Desired Result would be one array containing both arrays.

[
 {
 "productcode":"IRE10030CP",
 "FreeStock":"5",
 "ExpectedStock":""
 },
 {
 "productcode":"NIK10001",
 "FreeStock":"0",
 "ExpectedStock":""
 },

 {
 "productcode":"EK219SV150",
 "FreeStock":"1.00",
 "ExpectedStock":"20.00"
 },
 {
 "productcode":"ELTHMC50",
 "FreeStock":"-8.00",
 "ExpectedStock":"299.00"
 }
]

Thanks

Try just

union(array_1,array_2)

from a Compose action. See if it works.

We can confirm that

union(array_1,array_2)

works properly.

See this example.

assume array_1 and array_2 are in your format.

You would define the merging of arrays "array_1" and "array_2" as follows:

In our example we only have one item in our json schema "title" but it would be still applicable in your case or for any similar case.

Here is the result (see very bottom of the below screenshot - notice both arrays are merged into one array):

Hope this helps.

Thank you. Union is what i needed. Is there a source which lists all functions supported in Flow?
