Automatically merge two lists of records by a shared ID

Combines two separate data lists into one, matching rows by a common ID so nothing gets duplicated or missed.

How the work actually flows

It branches. Every path runs; all paths must finish before it continues; runs once per one per row in each list.

Pattern: Parallel Split (2) ยท Synchronisation (3)

The problem it solves

When you keep customer or order information in two different places, matching it up by hand is slow and error-prone. You end up with duplicate rows or missing matches that take time to untangle.

Who it fits

Operations or admin staff who regularly combine records from two different lists or systems.

How it works

  1. Two lists of records come in, for example from two spreadsheets or exports
  2. Each list is checked to make sure every row is treated as its own record
  3. The system matches rows between the two lists using a shared ID
  4. Matching rows are combined into a single, complete record
What you get

Records combined without duplicates or gaps

Two separate lists get matched and merged by their shared ID, so your records stay complete and nothing gets counted twice.

What you get

One combined list where matching records from both sources are merged into single rows.

What you need

Whatever accounts hold your two data sources, most commonly a Google account for Google Sheets.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.
