Sync Excel Column Across Languages

I have one master text column in an Excel workbook that feeds about twenty-five different language versions spread through the same file. Right now, every language cell is filled by hand, so whenever I adjust the English source text I have to hunt through each translated column and update it manually.

What I need is a clean way for any text change I make in that master column to cascade automatically to all of the other language columns. Whether you solve it with formulas, named ranges, Power Query, or a quick VBA macro is up to you—the only requirement is that the result works reliably in the current workbook structure and is easy for me to maintain.

Please deliver:
• The updated workbook with the automation in place
• A brief note (or short Loom video if you prefer) showing where the logic lives so I can extend it later

Everything else about the file stays as is; we are not touching formats or formulas outside this scope. If you have questions about sheet layout or need a sample row, let me know and I’ll send it right away.
