Hyo Jin Song ,

I don’t think you can do that with the Bilingual Excel filetype.

Unless other people gives more ideas, this is what I do:

In Excel, copy column a to B (and C to D).

In Excel, set column A with red text (same to C column):

In Trados Studio, open the standard Excel fietype > Content processsing section, and exclude text with that red colour:

Open the spreadsheet in Trados Studio (columns A and C shoud not be extracted) and translate as usual.

After generating the target document, open the translated spreadsheet in Excel, select columns A and C and set them as Automatic before delivering to the client:

Wow, sounds great~ I haven't tried it yet, but it seems like it will work well. Thank you so much~ 

I did as you instructed, and I was able to get the file (target) I wanted. Are you a genius? You're truly amazing. Thank you.

Glad it worked! I am just wondering if other colleages have a different way to do it…
