Automate location tagging across your margin report with one intelligent formula

If you're managing a margin report with multiple locations and accounts, you can streamline your data by using a formula to populate location names until the next one appears.

This user's problem is not a workaround request. It is a blueprint for how spreadsheets should work. They have a margin report where locations appear once, followed by a list of accounts, and they need every account row to carry its location label so they can filter or pull data by location. That is a fundamentally reasonable need. Yet the tools most people use force them to write a formula that scans upward, checks for blanks, and manually assigns context. That is not a spreadsheet doing its job. That is a spreadsheet making the user do the heavy lifting.

What the user is describing is a pattern that appears constantly in real-world reporting: hierarchical data flattened into a single column. A header row, then detail rows, then the next header. The formula they envision, something that reads column A, matches known location names, and fills column H until the next match, is simple in concept but surprisingly difficult in traditional spreadsheet logic. It requires nested IFs, helper columns, or array formulas that break the moment someone sorts the data. The user knows what they need, but the tool offers no native way to say, "Treat this column as a repeating group header." That is a failure of design, not of effort.

We see this as a clear opportunity for AI-native spreadsheets to step in. Instead of asking the user to build a cascading lookup, a smarter system could infer the structure: recognize that "Chicago" and "Dallas" are location headers, understand that the blank cells below belong to the nearest header above, and populate the location column automatically. The user already has a list of locations. The pattern is obvious. The only missing piece is a tool that understands context the way a human does. That is not futuristic. That is a feature that should exist today.

Our take is straightforward: stop writing formulas that work around your data's structure and start expecting your tools to read it. If you are spending time filling location tags down a column because your report came from a legacy export, you are not solving a problem, you are compensating for one. The user's request is a small, specific ask, but it points to a much larger shift. We want spreadsheets that see the pattern, not spreadsheets that wait for you to explain it cell by cell.

I have a margin report that has a header and accounts listed for separate locations. I need a formula that will read that first column and recognize the locations ( I can create a list) and list that location for every account until it finds the next location. My goal is something that looks like column H. I need the locations listed in column H so that I can pull specific accounts from the report and know what location it applies to. My screenshot is a shortened and condensed version of this report, but it shows how the location shows…
