Collection Processors for Flow (Sort, Filter, Find, Join, Map, and more)

This package contains new Flow actions that are designed to manipulate any SObject or collection of SObjects. This means that in one Flow you might use them with a collection of Accounts and in another flow a collection of Leads.

This Post was most recently updated on: 5/16/23
Current Version: 3.1.1

Note: If you are defining record collection variables in your flow and do not assign any value to them, many of these actions will fail with a “Missing required input parameter” when called from the flow. If there is a chance that your flow logic could bypass any assignment to the variable, be sure to add an Assignment element setting the collection variable to nothing before calling the action.

Notes on Dynamic Inputs

Keep in mind that you can insert mergefields as dynamic inputs in these actions. A mergefield takes the form of a reference name surrounded by braces and an exlamation point: {!myUpstreamVar}. So for example, you can use Map Collection like this:

Rating” : “Warm”, “Industry” : “Banking

or like this:

Rating” : “Warm”, “Industry” : “{!myUpstreamVar}

To get the syntax right, use this rule: Flow Builder will replace everything between braces before passing the inputs to the invocable action.

Add or Insert Record

Takes as input a collection of records and a single record, and an optional index value. Returns the combined collection. If the index value is specified and is less than the length of the inputCollection, the


List<SObject> inputCollection;

SObject inputRecord

Integer index


List<SObject> outputCollection;

Collection Calculate

Allows Add, Multply, and Average aggregate operations across a collection of records.

See documentation

Copy Collection

Takes as input a collection of records and returns the collection as output, allowing a new variable or reference to have the same value


List<SObject> inputCollection;


List<SObject> outputCollection;

Count Records And Fields

Takes a collection of records and returns a count. Optionally also takes a field name and a field value, and then also counts the number of records that have that particular value for that particular field. Returns both the number of matches and the total number of records. Added in V


List<SObject> inputCollection;

String fieldName;

String fieldValue;


Integer totalNumber

Integer matchedNumber

String errors

Dedupe Record Collection

Returns a set of de-duped records based on the field you specify. More Information


Clones a record and one or more sets of its child related records. More Information

Extract Strings From Collection (with Dedupe)

Takes a collection and a field name, and returns a list of strings reflecting the values of those fields for the records. For example, if you pass in a list of Contacts and a fieldName of “Id”, you’ll get back a list of recordIds for the contacts.


  • Extract a text collection or comma-separated string of any field for each record in a Record Collection
    • Particularly useful for Ids, Picklists, Multi-select picklists
  • Optionally de-dupe the values returned from all of the records.
    • Supports Multi-select picklists across all records in the collection
  • Useful when paired with the new AddQuotesToFields and ExecuteSOQL actions to pass in a set of strings wrapped in quotes
  • Ex. Select Name, Email from Contact where Id in (‘003023044333sDl’, ‘003023044333sKF’)


  • inputRecordCollection
    • List of records to extract field values from
  • fieldAPIName;
    • API Name of the field you want returned
  • dedupeValues;
    • If true only unique values will be returned. The default value is true


  • fieldValueCollection
    • Extracted fields in a text collection
  • fieldValueString;
    • Extracted fields in a comma-separated text variable

Filter Collection

Filters a collection against a formula string which can be created by an included Expression Builder Flow Screen Component.


List<SObject> inputCollection;

String formula;


String errors;
List<SObject> outputCollection;


For each member of the inputCollection, this action will evaluate the provided formula and add the member to the outputCollection if the formula is true.

The formula must be a string that can be processed by the Salesforce formula engine. The actual engine that evaluates this string is written in Apex and is included in the Collection Processors package.

It will use the recordId of the current member as context, replacing expressions in the formula string of the form $Record.fieldname. For example, if the formula is ‘$Record.Age__c > 21’ and the input Collection is a collection of Student__c, the evaluator will do the following:

Loop through the collection of Student records. For each record:

  1. use its ID and retrieve the record
  2. retrieve the values of any fields present in the formula string
  3. use the formula evaluator to evaluate the formula
  4. If the formula evaluates to true, add the current record to the output collection

Also see ‘Notes on Dynamic Inputs‘ at the top of this post.

Find Record in Collection

Returns all records from the inputCollection that have a field with name targetField that has a value of targetValue. Pass in the name of the object in targetObject (for example, if the inputCollection is a List of Contacts, set targetObject to Contact. There’s probably a way to determine this automatically but it’s not implemented in the action at this time). If there’s just a single result, the result is returned as singleOutputMember. Otherwise it’s returned as multipleOutputMembers. Version 1.20+: MultipleOutputMembers returns null if there are no results


List<SObject> inputCollection;

String targetObject

String targetField

String targetValue


SObject singleOutputMember;

List<SObject> multipleOutputMembers

Find Common and Uncommon Records

Compares & Contrats two record collections – even different sObject Types!

Generate Collection Report

Given a collection and a comma-separated list of field names, generates a string that includes all of the field values for every member of the collection. There are now two modes you can use. displayMode ‘simple’ simply throws the information out in simple groups. Useful for some debugging. displayMode ‘table’ generates HTML table markup that’s great for insertion into emails:

For full information on this action, see this post.

List<SObject> inputCollection;
String shownFieldsa comma-separated list of the fields you want to show in the table. Make sure to use the full api names, including ‘__c’ for custom fields.
displayMode‘simple’ or ‘table’. defaults to simple
tableStyleStringwill be inserted into the table html as a style attribute: <table style=”[tableStyleString]”>
headerStyleStringwill be inserted into the <th> tags as a style attribute
rowStyleStringwill be inserted into individual row tags (<tr>) as a style attribute

String reportString

Get Child Collection

Takes a record and returns a specified collection of child records related to the input record.

Pass in either a record or a recordID (as a string), but not both. Specify the childRelationshipName, which should be the name of the child Object. Example. If you have an Opportunity and want to retrieve all of the OpportunityContactRoles associated with the input, specify a childRelationshipName of OpportunityContactRole. Note that this should also be specified as the Output Collection.

In childRecordFieldsCSV, specify the fields you want returned as a comma-delimited string. Example: Id,Name

For more information, see


SObject inputRecord;
String inputRecordId;
String childRelationshipName;
String childRecordFieldsCSV;


List<SObject> childCollection;
String errorText;

Get First

Returns the first member of the inputCollection. The inputCollection is not modified by this action. Make sure that the types of your inputCollection and outputMember match.


List<SObject> inputCollection;


SObject outputMember;

Get Lookup Collection

Takes a collection of records and the name of an object related via a Lookup, and returns a collection of objects.

Pass in either a collection of records or a collection of string record ID’s. Pass in the name of the related object. Example: You start with a collection of OpportunityContactRoles and you want to get the Contacts associated with your OpportunityContactRoles via the ContactId Lookup field. In this case you would set lookupObjectName to Contact.

In lookupRecordFieldsCSV, specify the fields you want returned as a comma-delimited string. Example: Id,Name

For more information, see


List<SObject> inputCollection;
List<String> inputIds;
String lookupRecordFieldsCSV;
String lookupObjectName;


List<SObject> lookupCollection;
String errorText;

Get Records from Ids

The Collection Actions package of utility actions now has a new action that takes a collection of recordIds (i.e. a List of Strings) and returns the corresponding records. It carries out a SOQL query and obtains the fields that you specify by name. The records are returned both as a collection of records and a serialized (JSON) string.


String objectName;
String fieldNames;
global List<String> inputIds;


List<SObject> records

String recordString

More information.

Join Collections

Takes two collections (of the same type, please!) and returns their union as a single collection.


List<SObject> inputCollection1;

List<SObject> inputCollection2;


List<SObject> outputCollection;

Map Collection

Takes a collection and a set of key value pairs. Example:

Rating” : “Warm”, “Industry” : “Banking

Goes through the collection and changes each field with a name matching the key to the specified value.

Note that dynamic inputs are supported: “Rating” : “Warm”, “Industry” : “{!myUpstreamVar}“. See above for more.

NOTE: this currently only works for string values.


List<SObject> inputCollection;

String keyValuePairs;


List<SObject> outputCollection;

String errors;

Map Collection supports mapping of Time fields.

The Account object has a time field, and you want to use that time field on every case created. You can get the time variable from the Account and convert that to a string by using a formula, TEXT(Account.TIME). Then use that formula variable to assign that to the case.

Remove Record from Collection

Takes a collection and an index integer. Uses the Apex List class remove method to remove the member of the collection at the index location.


List<SObject> inputCollection;

Integer index;


List<SObject> outputCollection;

Return First N Records from Collection

Takes a collection and an integer count and returns that count of records from the beginning of the collection. The entire collection will be returned if it doesn’t contain more records than the record count attribute.


List<SObject> Input Collection;

Integer Record Count;


List<SObject> Output Collection;

Integer Return Count;

Sort Collection

Takes a collection and a sortKeys string formatted as key value pairs (example:


Known Issues:

1. Picklist fields are not supported.
2. If some of the records in your collection have a blank value for the field you’re sorting on, it will display the blank ones first no matter which direction you sort
3. The sorting priority is reversed from what I would have thought. It sorts first on the last key pair and then works backwards to the first.


List<SObject> inputCollection;

String sortKeys;


List<SObject> outputCollection;


Upsert will either save or update a collection, depending on whether the collection already has ID’s

serializedRecordDataString. This should be a JSON string of key value pairs where the keys are the names of fields on a single object. for example: {‘AnnualRevenue’: ‘400000’, ‘Rating’: ‘Hot’}
objectNameString. the name of the object that the serialized key value pairs belong to. Example ‘Case’. Only used to classify a passed in serializedRecordData

Map more than stringsAdd at least number and date to the mapping.I suppose the tricky bet is how to describe the value of the mapping pair. I suggest leaving it as text and converting to number and converting to date inside the map code.Terry ColeMapping of text area works. Mapping of picklist value works (from string). Mapping of long text area seems to generate fault. Mapping of number (from string) and date (from string) runs but does not make changes.
Count Records and FieldsDocumentation says field and value are optional, but screen configuration shows them as requiredJust wants a quick count. Can so with collection count feature of assign, however. Just wanted cleaner solution.
Minimum dateInsert a list of dates, and returns the minimum. Quite cumbersom via formulas, seems easier in apexCollection of dates
Strip NullsRemove null records from a record collectionCollection of sObject recordsNew collection of sObjects with null records removedCharles ThompsonAnything you can do to avoid a loop is great! As it is, to remove null records, it appears you have to compare each record against a single record variable (of the same sObject) that has not been initialised.
Get Child CollectionsPass in a *collection of records* and get a single collection of *the children of all of the input records* of a particular object type1) Collection of object records (or list of IDs)
2) Name of child object
Collection of records of the object type specifiedRachel BeachBasically “Get Child Collection” but you can pass in a list of records rather than having to create a loop and call the action for each parent record
Get Records where Field in CollectionGet all records where a field is equal to one of the values in a collection (select * from [object] where [field] IN [input collection])1) Name of object
2) Name of lookup field
3) Collection of record IDs
Collection of records of the object type specifiedRachel BeachNot sure if this needs to be different for lookup fields vs other types of fields but I personally want it for a lookup field
