The Scenario
You are a financial analyst. It is 7:45 AM on a Monday and your portfolio review is at 9 AM. Two hundred stock tickers sit in column A of a Google Sheet, collected over the weekend from three different watchlists. You need current price, market cap, and latest EPS in columns B, C, and D before the meeting starts.
The bad version of this morning:
- You open the API Ninjas stock endpoint in your browser
- You call it for the first ticker, read the JSON, find the three fields you need, paste each into B2, C2, D2
- You repeat for ticker two
- By ticker fifteen you are misaligning rows
- By ticker forty you are copying market cap into the EPS column
- You walk into the 9 AM with sixty rows done and 140 blank.
The fast version is one prompt and the whole column fills while you pour a second coffee.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet. It reads your ticker list and calls API Ninjas for every row, then writes the results back into the columns you describe.
Open the SheetXAI sidebar and type:
For every ticker in column A, fetch the current stock price, market cap, and latest EPS from API Ninjas and write the results into columns B, C, and D. If a ticker returns no data, write "N/A" in each column and flag the row yellow.
SheetXAI loops through all 200 rows, calls the API Ninjas stock endpoint for each, unpacks the three fields you named, and writes them back. The whole pass runs in the background.
What You Get
A fully populated watchlist with three enrichment columns:
- Column B: Current price — live at the time of the run
- Column C: Market cap — in the API Ninjas standard unit
- Column D: Latest EPS — most recently reported figure
- Flagged rows — any ticker that returned no data is visually marked so you know to investigate
The data is grounded in the actual API response, not interpolated or cached. If a ticker is newly listed or delisted, the flag tells you, it does not silently fill wrong data.
Want the S&P 500 constituent list pulled in fresh and matched against your watchlist? Ask in the same prompt, SheetXAI can pull the constituent list from API Ninjas and join it with what you already have.
What If the Data Is Not Quite Ready
Real ticker lists have edge cases. SheetXAI handles them inline.
When ticker symbols have inconsistent formatting
Your watchlist came from three sources, some have the exchange prefix (NASDAQ:AAPL), some don't (AAPL), some are lowercase.
Normalize all tickers in column A to uppercase symbols without exchange prefix. Then fetch price, market cap, and EPS from API Ninjas and write into columns B, C, and D.
When you only want data for tickers above a market cap threshold
You want to skip micro-caps below $500M for this analysis.
For every ticker in column A, fetch market cap from API Ninjas and write it into column B. If market cap is below 500000000, mark column C "SKIP" and leave D and E blank. For tickers above the threshold, fetch current price and EPS and write into columns D and E.
When you need both live price and the S&P 500 list
You want to know which of your tickers are S&P 500 constituents before you present.
Pull the S&P 500 constituent list from API Ninjas and paste it into a new sheet called SP500 with columns for ticker, company name, and sector. Then go back to the main sheet, check each ticker in column A against the SP500 sheet, and write "S&P 500" or "Non-index" into column E.
When the full enrichment is one prompt
You have raw tickers, no formatting, no filtering, and you need a clean enrichment-plus-analysis run in one shot.
Normalize the tickers in column A to uppercase with no prefix. Fetch current price, market cap, and EPS from API Ninjas for each. Write into columns B–D. Mark any ticker with market cap under 500M in column E as "Small Cap." Flag N/A rows in column F. Then calculate the average EPS across all valid rows and put it in cell H1 with the label "Portfolio Avg EPS."
The pattern: instead of cleaning first and enriching second, you clean and enrich in one instruction. SheetXAI handles the sequencing.
