Description:

When we are automating any task we may required inserting columns between other columns or left/right side of a column using Excel VBA.

For example, we may generate employee performance report based on their tenure in an organization. The first column would be ‘Employee ID’ and the last column would be ‘Tenure (in months)’. Between these two columns I want Employee performance for each month. We can automate this and we need to add the number of column between these existing tow columns based on the tenure of the particular employee. Since one employee may working from last 2 years, some one lease may be joined 2 months back.

So, while generating the reports for each employee, we need to add the number of columns as per their tenure. We will see this practically in the below example.
