How to Connect Brex to Excel (4 Methods Compared)

The Problem with Getting Brex Data Into Your Workbook

You run spend management in Brex: corporate cards, budgets, vendor payments, expense tracking. The data is there, in Brex's dashboard, but when your CFO asks for a burn-rate snapshot before the board call, or when HR sends a list of fifteen new hires who all need cards, you are the one who has to bridge the gap between Brex and Excel.

The usual path is a CSV export from Brex, opened in Excel, cleaned, and reformatted. For a one-off request that is annoying. For a monthly close it is a recurring tax. And when you need to push data back, issuing cards, creating vendors, updating spend limits, the CSV import path in Brex either does not exist for that operation or requires a support request.

Excel users have an extra wrinkle: if your workbook lives on OneDrive or SharePoint, the file is accessible from the web, but the Brex dashboard and Excel desktop are still two separate browser tabs. The export-and-paste loop is the same whether you are on a Mac or a Windows machine.

Below are the four common ways people work between Brex and Excel. Only the last one handles both directions.

Method 1: Export CSVs and Import Into Excel

The default. You filter what you want in Brex, click Export, download the CSV, open Excel, and import the file. Then you clean columns, convert amount strings to numbers, reformat dates, and drop whatever Brex added that you did not ask for.

When this works:

• A one-time snapshot you only need once
• A small export with consistent columns
• A report your team has been running the same way for two years

When it breaks:

• Monthly close where the same export-clean-format cycle happens every four weeks
• Anything that requires pushing data back to Brex — CSV import is not available for cards, vendors, or custom fields
• Exports that span multiple periods and need to be combined into one workbook
• Reports that need to cross-reference Brex against your accounting system

The core problem is asymmetry: Brex lets you export most things but import almost nothing. Half your workflow is manual in Brex, the other half is manual in Excel.

Method 2: Use Power Automate to Sync Brex Events

If your Excel files live on OneDrive or SharePoint, Power Automate is the obvious next step. You build a flow that listens for Brex events, a new expense, a settled transaction, a card limit change, and writes a row into your Excel workbook automatically.

This works for event-driven moments:

• New expense submitted → append to a running log in the workbook
• Transaction settled → add to the monthly register tab
• Card issued → update the cardholder tracking tab

This fails for batch or analytical work:

• A full audit of all expenses missing receipts over the past year
• A burn-rate snapshot of all active budgets as of today
• Bulk-creating vendors or cards from a list in the workbook

Power Automate fires on events, one row at a time. It does not go back and retrieve history, it does not aggregate across your full expense list, and it cannot write data back into Brex in bulk. Each run costs against your connector credits, and a high-volume month will run the meter.

Method 3: The Previous Generation — Finance Data Connector Add-Ins

Until recently, the best option for pulling Brex data into Excel was a category of finance connector add-ins. You authenticated, picked a data object, configured the column mapping, and scheduled a refresh. The workbook would update on its own each morning without you touching the export.

That was a real step up from downloading CSVs. The data was fresh, the refresh was automatic, and the team did not have to repeat the export every month.

But you were still responsible for the schema, the column mapping, and the downstream analysis. The add-in got the raw data in, but it did not calculate budget remaining as limit minus spent, it did not flag rows without receipts, and it could not push anything back into Brex. It also struggled with the Excel desktop to cloud gap — a workbook refresh that required the desktop app to be open was not actually automatic.

This is the category we think of as the previous generation. It worked for the read side, but it asked a lot of the operator and could not write back.

The Easy Way: Using SheetXAI in Excel

There is a different way entirely. SheetXAI is an AI agent that lives inside your Excel workbook, both on Excel for the web and Excel desktop. It reads the workbook, understands what you are trying to accomplish, and through its built-in Brex integration it can pull data out of Brex, push data into Brex, do analysis on the results, and write everything back to the workbook, in one prompt. No CSV, no Power Automate flow, no add-in to configure.

Example 1: Your Data Is Already in the Workbook

You have an Excel workbook with a Corrections tab, columns for expense ID, corrected memo, and updated department code. A hundred rows that need to be pushed to Brex.

For every row in the Corrections tab with an expense ID in column A, update the Brex expense memo with the value in column B and set the department to the value in column C. Write "Updated" or the error reason into column D for each row.

SheetXAI reads the Corrections tab, calls Brex for each row, and writes the status back into column D. One hundred expenses corrected, one column of confirmation, no Brex UI required.

Example 2: Your Data Lives in Brex

You need a budget burn-rate report for the board meeting and nothing exists in Excel yet.

Pull all active Brex budgets into the Budget Summary tab of this workbook, including budget name, owner, period type, total limit, amount spent to date, and remaining balance. Add a column calculating the spend percentage for each budget. Flag any budget over 80% spent in column G.

SheetXAI calls Brex, retrieves every active budget, writes the rows into the Budget Summary tab, calculates the percentages, and adds the flags. One prompt, end to end, from empty tab to board-ready report.

Which Method Should You Use

For a genuine one-off export where you only need the data once and you have time to clean it, the CSV path is fine. For event-driven logging where a new transaction should automatically append to a running register, Power Automate is a reasonable fit.

For anything that requires reading from Brex, doing analysis, writing back to the workbook, or pushing data into Brex in bulk, SheetXAI is the only option that handles all four operations in one prompt.

If you do monthly closes, quarterly audits, or regular card issuance for new hires, the second run pays back the setup of the first.

Try It

Get the 7-day free trial of SheetXAI and open any Excel workbook, then ask it to pull your Brex transactions or budgets into a tab. The Brex integration is included in every plan.
