The Scenario
You are a finance analyst. The accounting team is in the middle of the month-end close. One hundred expense entries in Brex have wrong memos or department codes. Your controller handed you an Excel workbook with the corrected data: expense ID, the right memo, and the correct department code. Push all the 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, save
- Repeat a hundred times
- Submit four with the wrong memo because you were copying from the wrong row
- Go back and find which four.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the correction workbook and pushes every update to Brex without you opening a single expense record.
Open the SheetXAI sidebar and type:
For every row in this workbook 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 for each, and writes the result into column D. 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 — expense ID not found, department invalid, etc.
The updates come from the workbook, not from your clipboard. No transposition errors.
What If the Data Is Not Quite Ready
Correction workbooks from accounting are rarely pristine. SheetXAI handles edge cases inline.
When some rows only need the memo updated
Column C is blank for thirty rows where the department was already correct.
For every row with an expense ID in column A, update the Brex memo with column B. If column C has a value, also update the department. If column C is blank, leave the department unchanged. Write the result into column D.
When expense IDs have trailing spaces or formatting issues
IDs were copied from a PDF and some have extra whitespace.
Before updating, 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 memo from column B and department from column C. Write the cleaned ID and result into columns D and E.
When the department values use display names, not Brex IDs
The accounting team wrote "Engineering" and "Sales" 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. Update each Brex expense using the matched 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 four fields per row in one pass
The full correction workbook has expense ID, memo, department, category, and location.
For every row in this workbook, 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 that failed.
The pattern: the workbook is the instruction set. SheetXAI reads it and executes row by row.
Try It
Get the 7-day free trial of SheetXAI and open the correction workbook 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 in Excel or the Brex in Excel overview.
