The Scenario
It's Sunday evening and you're doing your weekly portfolio prep. You have 12 altcoins in column A of your 'Portfolio' sheet — symbols you've held for months, some you added last week. Before you size your positions for the coming week, you want to know which of those coins have major catalysts on the calendar: mainnet launches, exchange listings, partnership reveals, anything that might move price.
The bad version:
- Open CoinMarketCal, search for coin #1, scroll through the next 30 days of events, manually copy the ones that look significant into your sheet — getting the date format right, assigning a category, not losing your place.
- Repeat that for all 12 coins, watching the tab count in your browser climb while your sheet fills up out of order.
- Spend another 20 minutes sorting by date and fixing the formatting on columns where the paste didn't land cleanly.
Two hours of prep work for what is fundamentally a lookup task. That's two hours that could have been analysis.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads your portfolio data and talks to CoinMarketCal for you — no tab-switching, no copy-paste, no column reformatting. You describe what you want, and it builds the table.
Fetch upcoming CoinMarketCal events for the coins listed in column A of my 'Portfolio' sheet, filter to events in the next 30 days, and write the coin name, event title, date, and category into my 'Upcoming Events' sheet sorted by date ascending
What You Get
- A new block of rows in the 'Upcoming Events' sheet, one row per event, sorted oldest-first.
- Column A: coin name as it appears in CoinMarketCal. Column B: event title. Column C: event date formatted as YYYY-MM-DD. Column D: category label (listing, mainnet, hard fork, partnership, etc.).
- If a coin in your portfolio has no events in the next 30 days, it gets skipped — no placeholder rows, no clutter.
- Events that couldn't be matched to a CoinMarketCal coin surface a note in a separate row so you know the lookup failed, rather than silently disappearing.
What If the Data Is Not Quite Ready
Your coin symbols don't match CoinMarketCal's naming convention
CoinMarketCal uses its own coin names, and your column A might have tickers, full names, or a mix of both. If the lookup is coming back empty for a coin you know is on the calendar:
The coins in column A of my 'Portfolio' sheet are in ticker format (BTC, ETH, SOL). Translate them to their full CoinMarketCal coin names, fetch upcoming events in the next 30 days for each, and write the results into my 'Upcoming Events' sheet with columns: coin name, ticker, event title, date, category
You want to filter by event category — only listings and mainnet launches
Not all calendar events carry the same weight. If you only care about the ones that historically move price:
Fetch upcoming CoinMarketCal events for the coins in column A of my 'Portfolio' sheet, return only events in the 'listing' or 'mainnet' categories, filter to the next 30 days, and write coin name, event title, date, and category into my 'Catalysts' sheet sorted by date
Your portfolio is split across two tabs — current holdings and watchlist
You want event coverage across both without merging them first:
Fetch upcoming CoinMarketCal events for coins listed in column A of my 'Holdings' sheet and column A of my 'Watchlist' sheet, combine the results, filter to events in the next 30 days, tag each row with which list the coin came from (Holdings or Watchlist), and write everything into my 'Upcoming Events' sheet sorted by date ascending
Full pre-trade briefing in one shot
The kill chain: data cleanup, event pull, and summary in one prompt.
Deduplicate the coin symbols in column A of my 'Portfolio' sheet (some may appear twice), translate any tickers to full CoinMarketCal coin names, fetch all upcoming events in the next 30 days for each coin, filter to events with a vote count above 20, and write a summary table to my 'Pre-Trade Brief' sheet with columns: coin, event title, date, category, vote count — sorted by vote count descending, then date ascending
The pattern: cleanup and retrieval in a single instruction means one pass, not three.
