Filter, split, and merge

Filter

The Filter node transforms a list or object. Pick an operation; the config shows only the fields that operation needs. The result lands in the output’s filtered field, with a count.

Operation	What it does	Key fields
Filter Array	Keep items matching a condition	Field to Filter (for arrays of objects), Operator, Filter Value, Case Sensitive
Remove Duplicates	Drop repeated items	Deduplication Field (optional, compares whole items if empty)
Limit	Keep the first N items	Limit, Offset (skip before limiting)
Sort	Order items	Sort Field, Sort Order (ascending/descending)
Filter Object	Keep or remove keys on an object	Keys to Keep, Keys to Remove (comma-separated)
Group by Field	Bucket items by a field value	Group By Field
Split String	Turn a string into a list	Delimiter, Trim Whitespace

Filter Array operators include equals, contains, starts/ends with, greater/less than (and or-equal), is empty / not empty, regex match, and in list / not in list (comma-separated values). Example: Filter Array on {{rss-1.items}} with Field to Filter title, Operator contains, Filter Value AI.

Split Out

The Split Out node turns a list into one item per element, so a downstream loop or node can handle each entry on its own. It outputs the elements in items, with a count.

Field	What it does
Input Data	The data to split: an array, or an object that holds the array field. Reference it like `{{node-id.items}}`.
Fields To Split Out	The field holding the array. Use dot notation for nested fields, and comma-separate to split several fields at once (they zip by index). Leave empty when Input Data is itself an array.
Include	Which of the input’s other fields to keep on each output item: No Other Fields, All Other Fields, or Selected Other Fields.
Fields To Include	When Include is Selected Other Fields, the comma-separated field names to keep.
Destination Field Name	Rename the split field on each output item (single field only).

Example: Split Out with Input Data {{http-1.response.results}} and Fields To Split Out empty turns a results array into one item per result, ready to feed a loop.

Merge

The Merge node combines data from multiple input branches into one list. It waits for all connected branches, pulls the list out of each input (it looks for common fields like data, items, filtered, collected_results), and outputs the result as merged.

Operation	What it does	Key fields
Append	Concatenate all inputs into one list	none
Combine by Position	Zip inputs together by index	none
Combine by Field	Join inputs on a shared field, like a SQL join	Match Field, Conflict Resolution (prefer first, prefer last, merge)
Keep Matches	Keep only items present in every input	Match Field (optional)
Remove Duplicates	Union of all inputs, deduplicated	Deduplication Field (optional)

Example: two API branches fetch users and subscriptions; Combine by Field on email joins them into one enriched list.
