The Scenario
Your web operations team owns a tracker sheet with 120 client website domains. The quarterly review is tomorrow. Someone on the leadership team forwarded a client complaint about a site being down, and now your director wants to know: which of these domains are currently returning errors, and which have redirect chains that aren't behaving as expected?
You found out about this at 4 PM.
The bad version:
- Open MX Toolbox HTTP lookup, paste the first domain, wait, read the status code and redirect chain, go back to the sheet, enter the values.
- Work through the list as fast as you can, skipping the redirect chain column for domains where it was too long to copy accurately.
- Run out of time at row 80 and show up to the quarterly review with 40 domains unchecked and a spreadsheet that looks like a work-in-progress.
The review is at 9 AM. You have 120 domains and four hours.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads your domain tracker and through its built-in MX Toolbox integration runs HTTP connectivity tests for every domain in the list, writing status codes, redirect information, and pass/fail results directly into the sheet.
Run an HTTP test via MXToolbox for every domain in column A and write the HTTP status code, redirect chain if any, and pass or fail result into columns B, C, and D
What You Get
- Column B: the HTTP status code returned for each domain — 200, 301, 404, 500, etc.
- Column C: the redirect chain if one was detected — blank for direct responses
- Column D: PASS if the domain resolved successfully, FAIL if it returned an error or was unreachable
- All 120 rows completed before you would have finished 20 manually
What If the Data Is Not Quite Ready
Need to distinguish HTTPS from HTTP failures
Run HTTP tests via MXToolbox for all domains in column A and write the HTTP status code in column B, whether HTTPS was properly reachable in column C, and any redirect chain in column D — mark column E as HTTPS-OK, HTTP-ONLY, or UNREACHABLE based on the results
Some domains have www and non-www variants in the list
Before running MXToolbox HTTP tests, flag any domains in column A that appear in both www and non-www form — mark the duplicate variant in column E as VARIANT, then run HTTP checks for all rows and write results into columns B, C, D
Errors need to be categorized by severity
Run MXToolbox HTTP tests for all domains in column A, write status codes into column B, and categorize each in column C as CLIENT-ERROR for 4xx codes, SERVER-ERROR for 5xx, REDIRECT for 3xx, or OK for 200 — sort so CLIENT-ERROR and SERVER-ERROR rows appear at the top
Pre-review sweep with actionable escalation flags
For all domains in column A, run MXToolbox HTTP tests, write status codes in column B and redirect chains in column C, then add a column D label — ESCALATE if status is 4xx or 5xx, MONITOR if there are unexpected redirects, and OK otherwise — and sort by column D so escalations appear first
Walk into the 9 AM review with a complete, sorted escalation list.
