Issue in taking Multiple Values(Comma Separated Values) in Action Tool

Question

Hi team,

Working on a query for action button attached to text box and mongo db tool.

I have formulated query for mongo db tool as attached below . But facing issues in creating a query for action tool, where #1 and #2 are dates, but now I have call multiple commas separated fields for #3 as updated in mogo db query already.

Comma separated field will look like – “Bin Fut 9:59:59 PM,Bitfin 10:59:59 AM,Blberg” . What should be updated while replacing #3 in action tool .

Hi @Sanskriti22,

Thanks for the clarification — now I see the #3 input is coming from a column of values (multi-row), not a single comma-separated string.

Here’s how to make that work:

* Use a Summarize Tool to Concatenate the Source field values using "," as the delimiter (and enable quote output).
* Use a Formula Tool to wrap the result like:

'["' + [Concatenated_Source] + '"]'
​

3. Connect that into your Action Tool, and replace "ABC" (or whatever placeholder you're using) in your Mongo query with this formatted array.

This will give you the correct $in array format like: ["Bin Fut 9:59:59 PM","Bitfin 10:59:59 AM","Blberg"]

I might have missed to mention this earlier csv field will called as it is but data in database is in tabular format for #3 - such as

Source

Bin Fut 9:59:59 PM

Bitfin 10:59:59 AM

Blberg

If i am taking above mentioned than mongo db query attached will not work - {"DateAndTime": { "$gte" : { "$date" : "2025-05-08T00:00:00.000+0000"} } },{ "DateAndTime": { "$lte" : { "$date" : "2025-05-08T00:00:00.000+0000"} } },{"Source":{ "$in": ["ABC", "XYZ", "DEF"] }

I will get multiple row item to be called from source column but those multiple columns are comma separated format for query of action tool .

I hope this will make issue more clear .

Hi @Sanskriti22,

If you're passing multiple comma-separated values (e.g., from a Text Box input like "Bin Fut 9:59:59 PM,Bitfin 10:59:59 AM,Blberg") into a MongoDB $in array via the Action Tool, you'll need to format those values properly as a JSON array.

Here’s how you can do it:

Replace(
  Replace(
    Replace([Destination], "2024-01-01", ToString([#1])),
    "2024-01-02", ToString([#2])
  ),
  "ABC", '["' + Replace(ToString([#3]), ",", '","') + '"]'
)

What it does:

* Wraps each value in quotes.
* Converts:
"Bin Fut 9:59:59 PM,Bitfin 10:59:59 AM,Blberg"
into
["Bin Fut 9:59:59 PM","Bitfin 10:59:59 AM","Blberg"]

This ensures your Mongo query receives a valid $in array when the Action Tool updates the query string.
