In Microsoft Excel, when you have a filtered column and want to paste data into the visible (filtered) cells only, you can use a technique known as the "visible cells only" or "filtered data" paste method. Here's how you can do it:

1. Filter the Column:

   • First, apply the filter to the column where you want to paste the data. Click on the filter drop-down arrow in the header of the column, and choose the criteria you want to filter by.

2. Select and Copy the Data:

   • Select the data you want to copy. You can use the usual copy method (Ctrl+C or right-click and select "Copy").

3. Move to the Destination Column:

   • Go to the column where you want to paste the data. Make sure the filter is still applied.

4. Paste Special - Visible Cells Only:

   • Use the "Paste Special" feature to paste the data into the visible cells only.
     • Right-click on the first cell where you want to paste the data.
     • From the context menu, choose "Paste Special."
     • In the Paste Special dialog box, select "Values" or the appropriate option based on your needs.
     • Check the option for "Skip Blanks." This ensures that only visible cells are affected.
     • Click "OK" to paste.

   Alternatively, after copying the data, you can use the keyboard shortcut Alt + E + S + V + Enter to paste values into visible cells only.

This method ensures that the data is pasted only into the cells that are currently visible due to the applied filter. Cells that are hidden by the filter will not be affected.

Keep in mind that if you're pasting formulas, you may need to adjust the formulas accordingly after pasting them into visible cells, as the references in the formulas may change based on the visibility of cells.
