The Scenario
You work on the network security team at a mid-size SaaS company. The threat intelligence lead asked you to pull a current ASN ranking — the top 500 Autonomous Systems by IPv4 address announcement volume — into an Excel workbook for a quarterly infrastructure risk review. They need ASN number, organization name, country of registration, and rank.
You've got the BigDataCloud API key. You've got a blank workbook. You've never called the ASN ranking endpoint before, and the documentation describes a JSON response with nested fields you'd need to flatten before anything lands usably in a spreadsheet.
The risk review presentation is Monday. It's Friday afternoon.
The bad version:
- Open BigDataCloud's API reference, find the ASN rank list endpoint, authenticate, run a test call.
- Realize the response is paginated and you need to handle multiple pages to get to 500 entries.
- Write a script, parse the nested fields, flatten the array, export as CSV, import into Excel — then discover the organization name field has encoding issues for certain international ASNs and spend an hour normalizing the text.
The one thing between you and leaving early on Friday is an API response you've never parsed before.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It connects to BigDataCloud on your behalf and pulls structured data directly into your worksheet based on a plain-language request — no endpoint configuration or JSON parsing required.
Open SheetXAI from the Excel add-in panel and type:
Fetch the global ASN rank list from BigDataCloud and write the top 500 entries to my ASN Research Excel sheet
What You Get
- Column A: ASN number (e.g., "AS15169")
- Column B: organization name
- Column C: country of registration
- Column D: rank by IPv4 announcement volume
- 500 rows filled, sorted by rank ascending, with a header row at row 1
What If the Data Is Not Quite Ready
You need fewer entries — the scope was narrowed to top 200 after the initial ask
Pull the top 200 ASNs ranked by IPv4 count from BigDataCloud and write ASN number, organization name, country, and rank into columns A through D on the ASN Research worksheet, replacing any existing data
The workbook already has last quarter's data and you want to append the new pull
Fetch the current top 200 ASN rankings from BigDataCloud — skip the first 5 rows (already filled with last quarter's data) and write the new results starting at row 6 with the same column format: ASN number, organization name, country, rank
You need the data filtered to a specific set of countries for the regional risk review
Fetch the top 500 ASNs by IPv4 count from BigDataCloud, write all results to columns A through D, then on a separate worksheet called "Regional Focus" copy only rows where the country is US, CN, RU, or DE
Full threat landscape setup in one pass
Pull the top 200 ASNs ranked by IPv4 volume from BigDataCloud into columns A through D — then add a column E that flags any ASN whose organization name matches entries in my "Known Bad Actors" worksheet (column A on that worksheet), and sort flagged rows to the top
One prompt handles the data pull, the cross-sheet lookup, the flag column, and the sort.
