In Airtable, I have two fields, each holding three distinct linked records. My goal is to merge the linked records from both fields into one field that encompasses all six unique linked records. I’ve attempted using a concatenate formula to achieve this, but it only provides the text representation and not the actual linked records. I’m seeking a way to automate this process using JavaScript or cell formulas, rather than manually inputting each of the six unique records.
You can achieve this by using Airtable’s scripting block if you’re open to using some JavaScript. Essentially, you would write a script that retrieves records from both of the linked fields, combines these arrays, and strips duplicates. Then, the script can update your chosen target field with the newly compiled list of linked records. This approach is beneficial because it utilizes Airtable’s API, allowing for automation while maintaining the integrity of linked data without converting it into plain text.
hey there! 
try the third-party tool “integromat”, now called “make”. it’s a no-coding-needed automation platform that can help sync and merge linked records across fields in airtable. quite handy if you want to avoid direct scriptiong! good luck!
You can definitely consider using the Airtable formula fields alongside rollup fields to achieve something similar, but with manual intervention. While it doesn’t directly merge linked records into a single field, you can create a rollup field that aggregates data from multiple linked record fields and leverages an aggregate function like ARRAYUNIQUE(). This will give you a unique list within the context of a single rollup field, from which you can comprehend unique linked records even if it requires manual observation to then update another field with the distinct records.
If you’re hesitant about diving into scripts or external tools, you might want to explore using Airtable Automations. Set up a Trigger to watch for updates on your fields, and follow it with an Action that runs a script to merge linked records. Use the scripting actions to fetch data from both fields, de-duplicate, and update your combined field automatically. It’s more integrated than third-party options and can keep your process within Airtable itself, avoiding text-only limitations.
