The Scenario
You are a finance analyst at a growth-stage startup. The accounting team is in the middle of the month-end close. Last week someone discovered that one hundred expense entries in Brex have wrong memos or were coded to the wrong department, because an employee who left in March submitted fifty of them under generic descriptions, and the rest were autocategorized incorrectly.
Your controller handed you an Excel sheet with the corrected data: expense ID, the right memo, and the correct department code. Your job is to push all one hundred fixes into Brex before the books close on Friday at 5 PM.
The slow version:
- Log into Brex, go to Expenses
- Search by expense ID, one at a time
- Click Edit, update the memo, update the department
- Click Save
- Move to the next row
- By row thirty you are making mistakes because the IDs all look similar
- You submit four of them with the wrong memo because you were copying from the wrong row in the sheet.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the correction sheet and pushes every update to Brex without you opening a single expense record.
Open the SheetXAI sidebar and type:
For every row in this sheet with an expense ID in column A, update that Brex expense: set the memo to the value in column B and set the department to the value in column C. Write "Updated" or the error message into column D for each row.
SheetXAI iterates through all one hundred rows, calls Brex's update endpoint for each, and writes the result into column D. You hand column D to the controller as the confirmation log.
What You Get
Column D with a status for every correction:
- "Updated" — memo and department pushed successfully
- Error message — if an expense ID was not found or the department value was invalid
The updates come from the sheet, not from your clipboard. Whatever is in column B goes to Brex as the memo. No transposition.
If three rows fail, the error messages tell you exactly why. Fix those three rows, re-run. The other ninety-seven are already done.
What If the Data Is Not Quite Ready
Correction sheets from accounting are rarely pristine. SheetXAI handles the edge cases inline.
When some rows only need the memo updated, not the department
Column C is blank for about thirty rows where the department was already correct.
For every row in this sheet with an expense ID in column A, update the Brex expense memo with the value in column B. If column C has a value, also update the department. If column C is blank, leave the department as-is. Write the result into column D.
When expense IDs in the sheet have trailing spaces or inconsistent formatting
The IDs were copied from a PDF and some have extra whitespace or dashes that Brex will not match.
Before updating any expenses, clean the expense IDs in column A: remove leading and trailing whitespace and any non-alphanumeric characters. Then update each Brex expense with the cleaned ID, setting the memo from column B and department from column C. Write the cleaned ID and the update result into columns D and E.
When the department values use display names, not Brex department IDs
The accounting team wrote "Engineering" and "Sales" in column C, but Brex expects internal department IDs.
Before updating expenses, look up each department name in column C against the Brex department list to get the correct department ID. Then update each Brex expense using the matched department ID and the memo from column B. Write the department ID used and the result into columns D and E.
When you need to update memos, departments, categories, and location in one pass
The full correction list has four fields to fix per row, not two.
For every row in this sheet, update the Brex expense in column A with: memo from column B, department from column C, expense category from column D, and location from column E. Write a summary result into column F showing which fields were updated and any fields that failed.
The pattern: the sheet is your source of truth. SheetXAI reads the instruction set and executes it row by row.
Try It
Get the 7-day free trial of SheetXAI and open the correction sheet your accounting team builds for each close cycle, then ask it to push all updates to Brex in one go. The Brex integration is included in every SheetXAI plan. See also how to export Brex expenses for an audit or the Brex in Google Sheets overview.
