The Scenario
You are a backend developer. Eight feature branches are in the queue for review, each with pending migrations. Before anything merges to main, you need to confirm that each branch's schema differs from main only in the expected ways.
The branch pair list is in an Excel workbook: column A has the project ID, column B has the feature branch ID, column C has the main branch ID. The architecture review is tomorrow at 10 AM.
The bad version of the next two hours:
- Connect to feature branch one
- Dump the schema
- Connect to main, dump that schema
- Diff the two outputs manually
- Read the diff, paste the relevant lines into the workbook
- Repeat seven more times
- Branch five has an unexpected index nobody documented
- You walk into the review with three branches unreviewed and an unexplained schema change in branch five.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the branch pair list from your workbook and calls the Neon API to compare schemas for each pair.
Open the SheetXAI sidebar and type:
Compare schemas between the branch pairs listed in my Excel sheet and write whether there are any schema differences (YES/NO) in column D and the full diff text in column E for each pair.
SheetXAI iterates through all eight rows, calls the Neon comparison API for each pair, and writes the results into columns D and E. All eight comparisons are complete before the review.
What You Get
A complete pre-merge review workbook with:
- Column D — YES or NO flag for each branch pair
- Column E — the full unified diff for inspection
- Consistent output format — same structure across all rows, easy to scan
Branches where the schema is identical get an explicit "NO" in column D, confirming the comparison ran rather than was skipped.
What If the Data Is Not Quite Ready
Review workbooks often need additional filtering before they are useful in a meeting. SheetXAI applies the logic in the same prompt.
When you want to flag unexpected changes automatically
Most branches should add exactly one new table. Anything beyond that needs a closer look.
Compare schemas for all branch pairs. In column D write YES/NO. In column E write the diff. In column F write 'REVIEW' for any diff showing more than one new object or any deleted or altered columns, and 'OK' for everything else.
When some rows are missing the target branch ID
A few rows only have the feature branch ID. You want to compare against the project's default main branch.
For any row where column C is blank, look up the default branch ID for the project in column A and use that as the comparison target. Then compare schemas for all rows and write the diff into column D.
When you want a summary for the architecture lead
The lead wants a single cell to screenshot before the meeting starts.
Compare schemas for all branch pairs. Write YES/NO into column D and the full diff into column E. Write a summary in cell G1 listing: total branches reviewed, number with differences, number flagged for closer review, and the branch IDs that need discussion.
When the review also needs sign-off tracking
The architecture lead wants to mark each row as approved or needs-discussion after the review.
Compare schemas for all branch pairs and write YES/NO into column D and the full diff into column E. Add a blank 'Decision' column F for the team to fill in during the review. Format rows where column D is YES with a yellow background so they stand out.
The pattern: one prompt produces the full comparison table. The review meeting works from the workbook, not from a terminal window.
