The Scenario
You are building a stock-lookup tool for the research team. The core of it is a reference table: every exchange that Marketstack supports, with the MIC code, exchange name, country, and city, so users can look up the right exchange for a given ticker before pulling data.
You could go to Marketstack's documentation and start copying exchange records by hand. The Marketstack site lists exchanges, but not in a format that lands cleanly in a workbook. And you need all of them — not a curated selection, not the major ones, all 72+ exchanges — so the tool is complete when it ships.
The tool is supposed to go live by end of week.
The bad version:
- Call Marketstack's exchanges endpoint, get the first page of results, count how many records came back, and realize pagination is required to get the full list
- Copy the first page of records into the workbook, then manually call the next page, copy those, repeat until you have hit every page and assembled the full table
- Discover that the city field is missing for a handful of exchanges and decide whether to leave those cells blank or fill them manually from the exchange's website
The reference table is infrastructure for the actual tool. It should not take most of a workday to build.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook context and through its Marketstack integration it can fetch the complete exchange catalog — all pages — and write it into the workbook in one operation.
Pull the full list of Marketstack exchanges into this Excel workbook with columns for MIC code, exchange name, country, and city, sorted alphabetically by country
What You Get
- One row per exchange across the full Marketstack catalog
- Four columns: MIC Code, Exchange Name, Country, City
- Sorted alphabetically by country so the table is easy to scan and filter
- Exchanges with missing city data get a blank cell rather than an error, keeping the table clean
What If the Data Is Not Quite Ready
You want a fifth column for the exchange website URL
Fetch all supported exchanges from Marketstack and write MIC code, exchange name, country, city, and website URL into this workbook — one exchange per row, sorted by country
You only want exchanges that are currently active
Fetch all Marketstack exchanges and write MIC, name, country, and city — include only exchanges where the status is active, and add a note in a separate row counting how many active exchanges are in the list
You want exchanges grouped by continent rather than sorted by country name
Fetch all Marketstack exchanges and write MIC code, name, country, continent, and city — group the rows by continent and sort alphabetically within each continent group
Full reference build: fetch all exchanges, add a country summary count, and add a lookup formula column
Fetch all Marketstack exchanges and write MIC, name, country, and city into a worksheet called Exchange Reference; add a Country Summary worksheet counting exchanges per country sorted by count descending; and add a formula in column E of the main worksheet that shows the total number of other exchanges in the same country as each row
Combining the catalog pull, the summary, and the formula in one prompt means the reference workbook is complete and navigable rather than just a raw data dump.
