When trying to create a Join with the following keys (two columns from a Sheet1 equals the same column from a Sheet2), I'm getting join.columns.unequalCount error.
Sheet1.A = Sheet2.A Sheet1.B = Sheet2.A
This is expected behavior for the current product design, the Join constructor does not support such conditions.
To work around this limitation one could:
- Apply a Filter in Sheet1 using an EQUALS function on #Sheet1#A and Sheet1!B. Advanced Filtering Tutorial.
- Use an SQL Sheet with a corresponding SQL query that represents the desired Join operation. The query example:
SELECT * FROM Sheet1
JOIN Sheet2 ON Sheet1.A = Sheet2.A OR Sheet1.B = Sheet2.A
