Who it is for

Who Excel automation
is built for.

01 Controllers and FP&A managers

Your week starts with exports, paste-special and a VLOOKUP that broke again over the weekend.

02 Office managers and bookkeepers

You assemble the same weekly report from five downloads and email it with a date in the file name.

03 Sales and operations leads

The owner wants a KPI sheet every Monday, and building it is a Sunday-evening job.

04 Owners without a BI tool or an analyst

Excel is the reporting system, and nobody has time to make it reliable.

Why manual reports in Excel
cost more than they look.

What is Excel automation?

Excel automation replaces the weekly routine behind every management report — export five CSVs, paste them into last period’s workbook, clean the dates and names, refresh the pivots, hope the formulas held, check the totals, write comments and email a dated copy — with a workflow that does the routine on a schedule. Finance teams spend far more time collecting and checking data than analysing it, and most of that work is the same every week. That is the part an automated reporting flow removes.

We build automated reports in Excel around the workbook you already have rather than a BI platform you have to migrate to. Data is pulled from QuickBooks Online, Xero, HubSpot, Stripe, bank feeds and ad accounts through their APIs, cleaned by rules written in a mapping table your team controls, and written into your template through the Microsoft Graph API. Control totals are compared with the source system before anything is sent; a mismatch holds the report and alerts the controller. A language model drafts the variance comments and an analyst edits them.

What changes when you automate reports in Excel

Automated reporting in Excel means the Monday report is in the inbox at 08:00 with the totals already reconciled, and the analyst’s morning goes into reading the numbers rather than assembling them. Format changes in a source stop the run instead of silently corrupting a tab. Definitions, judgement and the final word on every comment stay with finance.

The workflow

Automated reporting in Excel:
13 nodes, zero paste-special.

The run path of one scheduled report. Each report runs on its own; a person reads the comments and approves anything the checks flag.

Every node

Every node of the
Excel reporting workflow.

Collect & clean
01Trigger

Monday 07:00

A schedule starts each report; the same path can be started by a new CSV in a mailbox or a SharePoint folder.

02HTTP

Pull the sources

Fetches the period’s data from QuickBooks Online or Xero, HubSpot or Salesforce, Stripe, Google Ads and Meta through their APIs.

03Code

Normalise the data

Python with pandas fixes dates and currencies, removes duplicates and maps names through a mapping table your team maintains.

04Model call

Read the PDFs

Bank statements and supplier PDFs that arrive as documents are read by OCR and a language model into rows with the same columns.

05IF

Format changed?

If a source adds, renames or drops a column, the run stops before anything is written and a person gets the diff.

Build & check
06HTTP

Open the template

Copies the master workbook for the period in SharePoint or OneDrive through the Microsoft Graph API — your tabs, formulas and charts stay as they are.

07Code

Write the data tabs

Writes the clean rows into the data sheets with openpyxl; pivot tables and formulas recalculate on open.

08Code

Reconcile the totals

Compares the report’s control totals — revenue, cash, headcount — with the source systems.

09IF

Totals match?

Matching reports go on; a mismatch sends the figures and the gap to the controller in Teams and holds the send.

Explain & send
10Model call

Draft the comments

A language model receives the variance table and writes plain-English explanations of the biggest movements, citing the rows they came from.

11HTTP

Analyst review

The analyst gets the workbook and the draft comments in Teams or Slack and edits them before anyone else sees the report.

12Loop

Deliver to each recipient

For each recipient list, exports PDF or XLSX, sends by Outlook or Gmail, posts the summary in Teams and saves a dated version in SharePoint.

13Set

KPI thresholds

Sets alert rules on the updated data — cash below a floor, pipeline below target — and messages the owner when one is crossed.

Results

What good reporting looks like
and what we build toward.

Benchmarks from the DataRails survey of 200 CFOs and the AFP / APQC FP&A study: finance teams spend twice as much time collecting data as analysing it, and the gap between the two is the time an automated report gives back.

How we work

How an Excel automation project
runs, week by week.

Week 1Audit

We map the process as it runs today, count the minutes and agree what the flow must never do on its own.

Weeks 2–3Prototype

A working flow on your real data, in a sandbox. You see every run and every exception.

Weeks 3–6Launch

Edge cases, approvals and alerts, then the switch-over — with the old way kept as a fallback.

AfterSupport

Monitoring, fixes when a vendor changes a format, and a monthly report of hours saved.

FAQ

Excel automation questions
we hear every time.

Can we automate reports in Excel without leaving Excel?

Yes — that is the point. Your workbook, tabs, formulas and charts stay exactly as they are. The flow writes the data sheets through the Microsoft Graph API or openpyxl and the rest of the workbook recalculates, so the people who read the report notice nothing except that it arrives on time.

How is this different from VBA macros and Power Query?

Macros and Power Query run inside one workbook on one machine when someone opens it. An automated reporting flow runs on a server on a schedule, talks to QuickBooks, HubSpot or Stripe through their APIs, checks the totals and sends the result. Power Query can still be part of the template.

Which systems can be connected as data sources?

Anything with an API or an export: QuickBooks Online, Xero, NetSuite, HubSpot, Salesforce, Stripe, bank feeds, Google Ads and Meta, plus CSVs that land in a mailbox or a SharePoint folder. PDF statements are read by OCR and a language model.

What happens if the source data has an error or the file format changes?

The run stops before writing anything, and a person gets a message with the difference. Control totals are compared to the source system on every run, so a wrong number is held, not sent.

Will the language model invent figures in the comments?

The model only receives the variance table and writes explanations that cite the rows they came from; it does not calculate numbers. An analyst reads the draft before it goes to leadership.

Where does our financial data live and who can access it?

In your Microsoft 365 tenant or your own server. Access follows your existing SharePoint permissions, the flow runs in your account, and every step is logged. The model can run locally if the data must not leave your network.

How long does setup take, and what does support look like?

A first report is usually running within a few weeks, since the template already exists. After that, changes to sources or definitions are small edits to mapping tables, which your team can make without us.
