VBAtoPython helps finance, payroll, and analytics teams safely migrate fragile Excel macros into maintainable Python — without hallucinations, hidden changes, or code retention.
Not a demo toy. This is a controlled migration path designed for teams that need auditability.
See side-by-side VBA and Python with notes on what changed and why.
GoTo, On Error, resizing arrays, and complex flow are explicitly flagged for review.
In-memory conversion. No code retention. No training on your macros.
This is what a typical legacy macro looks like when modernized. The goal is not ‘pretty code’ — it’s reviewable logic and visible risk.
Example stats from a typical legacy module — yours will vary.
Excel VBA powered automation for decades — but today it’s a maintenance risk. Legacy macros are hard to test, hard to version properly, and often understood by only one person who no longer works here.
When something breaks, teams face a bad choice: rewrite everything by hand, or paste proprietary logic into generic AI tools and hope for the best. Neither option is acceptable in regulated, high-trust environments.
VBAtoPython analyzes real-world Excel VBA and produces deterministic Python drafts that preserve logic, expose risk, and are meant to be reviewed — not blindly executed.
If you work in finance, payroll, or accounting, silent hallucinations are unacceptable. VBAtoPython uses a deterministic parsing engine: identical VBA input produces identical Python output. Complex constructs are explicitly flagged so you can review and refactor safely.
Converted Python is structured to support multiple execution targets, including:
You’re not locked into a single runtime. The goal is future-safe Excel automation — not novelty.
It’s not for learning Python syntax. It’s for making Excel automation survivable.
VBA input
Sub SumColumn()
Dim total As Double
Dim i As Long
total = 0
For i = 2 To 100
total = total + Cells(i, 3).Value
Next i
MsgBox "Total: " & total
End SubPython output
def sum_column(ws, start_row: int = 2, end_row: int = 100, col: int = 3) -> float:
"""Sum numeric values in a single worksheet column."""
total: float = 0.0
for row in range(start_row, end_row + 1):
value = ws.cell(row=row, column=col).value
if isinstance(value, (int, float)):
total += float(value)
return totalThe live app will let you paste your own macros, inspect the generated Python, and export it into your projects.
If you need to migrate Excel VBA macros into Python without risking logic errors, privacy leaks, or unreviewable output, VBAtoPython gives you a controlled path forward.

This will become the interactive editor: paste VBA on the left, inspect Python on the right, and export code into your repo.
