The Scenario
Your domain registrar's support queue has 200 customer-reported DNS issues. Someone on the team exported them to a workbook last week. Nobody has touched the file since because nobody wants to spend a day in MX Toolbox running manual lookups. The backlog is now your problem, and leadership wants a triage summary by end of day.
The bad version:
- Open MX Toolbox DNS Health Check, paste the first domain, wait for the result, scan through nameserver records and any flagged warnings, switch to the workbook, manually type in the nameserver hostnames and overall status.
- Multiply that by 200. Realize by row 40 that you've been inconsistent about how you're recording nameservers with multiple values.
- Deliver a partially complete workbook at 5 PM and call it a triage draft.
Two hundred DNS lookups by hand is a full-day event. The triage summary leadership asked for cannot be built from a draft with 40 rows done.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads your domain list and through its built-in MX Toolbox integration runs DNS health checks for every domain in the column, writing nameserver records and status flags back to your workbook.
Run a DNS health check via MXToolbox for each domain in column A and write the nameserver hostnames, any failed checks, and overall DNS status — OK, WARNING, or ERROR — into columns B, C, D
What You Get
- Column B: nameserver hostnames for each domain, comma-separated if multiple
- Column C: any failed checks returned by MX Toolbox for that domain — blank if all passed
- Column D: overall DNS status — OK, WARNING, or ERROR — for fast visual triage
- 200 rows checked in the time it would have taken to do 10 manually
What If the Data Is Not Quite Ready
Domains have trailing spaces and mixed casing from the export
Clean each domain in column A — trim whitespace and convert to lowercase — before running MXToolbox DNS health checks, then write the nameservers, any failures, and status into columns B, C, D based on the cleaned values
Need to separate nameserver warnings from hard errors
Run DNS health checks for all domains in column A using MXToolbox, write the nameservers in column B, then split results into column C for WARNING-level issues and column D for ERROR-level issues, leaving those columns blank if no issues exist at that level
Some domains were already resolved in a prior audit column
Check column E for each row — if it already contains a DNS status from a previous audit, skip that row and leave it as-is; for all other rows, run a MXToolbox DNS health check and write results into columns B, C, D
Full triage sweep for end-of-day handoff
For all domains in column A, run MXToolbox DNS health checks, write nameservers into column B, failures into column C, and status into column D, then add a column E that labels each domain as ESCALATE if status is ERROR, MONITOR if WARNING, and RESOLVED if OK — sort by column E so ESCALATE rows appear first
Triage complete before the end of the day, with an escalation queue built in.
