append collection column to excel

blazino17 — Thu, 03 Apr 2025 19:36:07 GMT

How can I write data from a specific column in a collection and append it to a new Excel file in Blue Prism? Additionally, if the Excel file is created during the first run of the process, subsequent runs should append the column data to the existing file.

Hi @blazino17

Hope you are doing well,

First copy the columns of the main collection to a Temporary collection and follow below steps,

Delete the columns other than the "Required Column" from Temporary collection :

The output will be as follows :

Re: append collection column to excel

Now to append data from the extracted collection to the column in the excel lets say "Excel Column" below steps can be followed:

Once you open excel workbook search for Excel Column

Go to next empty cell down in that column

Now write the data from collection in that column, mark Include Column Names flag as False to exclude the column name from collection
