The Scenario
You are the finance controller at a fifty-person company. It is the first week of Q3. The executive team approved new spending limits for thirty employees, some got increases, some got decreases, based on updated headcount plans.
HR sent you a Google Sheet: column A is the Brex user ID, column B is the approved new monthly limit. Thirty rows. The limits need to be live in Brex before employees start submitting expenses next week.
The slow version:
- Open Brex admin, navigate to Users
- Search for user ID one by one
- Click into the user, find the spending limit field
- Update it to the new value
- Save
- Repeat thirty times
- Realize on user twenty-two that you set $5,000 for someone who should have gotten $500 because you misread the row
- Go back, fix user twenty-two, flag it for audit.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the limit sheet and updates every user in Brex without you touching the admin UI.
Open the SheetXAI sidebar and type:
For every row in this sheet with a Brex user ID in column A, set that user's monthly spending limit to the amount in column B. Write "Updated" or the error message into column C for each row.
SheetXAI iterates through all thirty rows, calls Brex's user update endpoint for each, and writes the result into column C. The updates are live before you close the sidebar.
What You Get
Column C with a confirmation for every row:
- "Updated" — limit applied successfully
- Error message — if the user ID was not found or the limit format was invalid
The limit values come from column B, not from memory. No misread rows, no decimal-place errors.
If any rows fail, the error tells you why. Fix those rows and re-run.
What If the Data Is Not Quite Ready
Q3 limit updates always come with caveats. SheetXAI handles the conditional logic inline.
When limits are in mixed number formats
Some rows have amounts as "$5,000," some as "5000," some as "5k." Brex expects a plain integer.
Normalize the spending limit in column B across all rows to a plain integer before updating. Remove dollar signs, commas, and "k" suffixes. Then set each Brex user's monthly spending limit to the normalized value. Write the normalized amount and the result into columns C and D.
When some users should have their card frozen instead of just a limit reduction
Column C in the sheet flags five employees with "Freeze" because their roles changed. Those users need card status set to inactive, not just a limit update.
For each row in this sheet, read column C. If column C is blank, update the user's monthly spending limit in Brex to the amount in column B. If column C says "Freeze," set the user's card status to inactive instead of updating the limit. Write the action taken and the result into column D.
When limit changes need to be logged with a reason
Your audit trail requires a reason code for every limit change. Column C in the sheet has the reason.
For every row in this sheet, update the Brex user's monthly spending limit to the amount in column B. Append the reason from column C as an internal note on the user record. Write "Updated with note" or the error into column D.
When you need to update limits and also reconcile against the previous limits
Your CFO wants a before-and-after view: what the limit was, what it is now, and the dollar delta.
For every row in this sheet, retrieve the current monthly spending limit from Brex for the user in column A. Write the current limit into column C. Then update the limit to the amount in column B. Write the new limit and the dollar change (new minus old) into columns D and E. Write the update result into column F.
The pattern: the sheet defines the policy. SheetXAI enforces it in Brex row by row.
