Column Mapping is a built-in preview that appears when you manually share a single item to another board. Before the item is added, SIMB compares the columns on both boards and shows you exactly which values will sync, which won’t, and which columns are missing on the destination board entirely. You can create any missing columns with a single click — right from the mapping window — before completing the share. This makes cross-board syncing predictable and eliminates the most common source of sync issues.
Column Mapping is only available when manually sharing a single item via the SIMB item view. It does not appear when using automations or batch actions — those flows skip the mapping step. If you rely on automations, use Column Mapping during a manual share first to align your boards.

​
What Column Mapping Shows

The mapping window categorizes every column on the source board into one of three states:
IndicatorMeaning
🟢 MatchColumn exists on both boards with the same name and same type — it will sync.
⚪ MismatchColumn exists on both boards but the name or type differs — it will not sync.
⚠️ MissingColumn exists on the source board but is absent from the destination board — it will not sync unless you create it.

​
Preview and Fix Column Alignment

1

Open the item you want to share

Click the item and navigate to the Same Item Multiple Boards tab inside the item view.
2

Select the destination board

Choose the board where you want the item to appear. SIMB will immediately fetch that board’s column structure.
3

Review the Column Mapping window

A mapping panel opens, showing every column categorized as matching, mismatched, or missing. Green indicators mark columns that will sync. Warnings flag anything that needs attention.
4

Create missing columns (optional but recommended)

For any column marked as missing, you’ll see a Create column button. Click it to automatically add that column to the destination board with the identical name and type. Repeat for each column you want to sync.
5

Add the item

Once you’re satisfied with the mapping, click Add Item. The item appears on the destination board and begins syncing all matched columns immediately.

​
Creating Missing Columns in One Click

When you click Create column next to a missing column, SIMB creates a new column on the destination board that:
  • Uses the exact same name as the source column
  • Uses the exact same column type (Status, Text, Date, People, etc.)
This means the newly created column is immediately eligible for syncing — no manual configuration required.
Run Column Mapping on a manual share before activating automations on the same board pair. Once your columns are aligned, automations will sync those columns correctly without any further setup.

​
Important Notes

  • Column names must match exactly — including capitalization and spacing. due date and Due Date are treated as different columns.
  • Column type must match. A Status column on one board will not sync with a Text column on another, even if the names are identical.
  • Mismatched columns simply don’t sync — no error is raised on the item.
  • Column Mapping does not apply to automations. Automations determine sync eligibility solely by comparing column names and types at the time the automation fires.
  • You can rename or edit columns after syncing has started, but if you change a name so it no longer matches, syncing for that column will stop.

​
Troubleshooting Tips

If a column isn’t syncing after sharing:

Check the exact name

Open both boards and confirm the column names are character-for-character identical, including case and spaces.

Confirm the column type

Both columns must be the same type. Rename isn’t enough — the type must also match (e.g., Status to Status, Date to Date).

Use Column Mapping to diagnose

Re-open the SIMB item view, select the destination board, and review the mapping window. It will clearly show any mismatch or missing column.

Check for unsupported types

Formula, Mirror, and Connected Boards columns are not supported for syncing. These will never appear as green in the mapping view.
