Turn messy legacy VBA into reviewable Python.
VBAtoPython takes your existing Excel macros, generates draft Python 3 equivalents, and explains what changed line by line. You stay in control of the logic without burning days on manual rewrites.
Sub CalculateTotals()
Dim total As Double
total = 0
For Each c In Range("B2:B25")
total = total + c.Value
Next c
Range("B26").Value = total
End Subdef calculate_totals(sheet):
# Vectorized = Instant ⚡
total = sheet["B2:B25"].sum()
# Write back result
sheet["B26"].value = totalBUILT FOR

Why convert legacy VBA to Python?
Excel VBA (Visual Basic for Applications) was the standard for automation for decades, but it has become a maintenance nightmare. Legacy macros are often single-threaded, hard to version control, and impossible to unit test.
By converting your Excel macros to Python, you unlock the power of modern data science libraries like Pandas, NumPy, and OpenPyXL. Python scripts run faster, handle datasets larger than Excel's 1-million-row limit, and integrate seamlessly with modern cloud stacks (AWS, Azure) and CI/CD pipelines.
Supported VBA Features
- Control Structures:
For...Nextloops,Do While, and complexIf...Elselogic. - Object Manipulation:
Range,Cells,Worksheets, andWorkbookevents. - Data Types: Automatic mapping of VBA Variants, Integers, and Strings to Python equivalents.
- Functions: Conversion of
Application.WorksheetFunction(VLOOKUP, SUMIF) to Pandas logic.
Smart Library Mapping
We don't just translate syntax; we map intent. VBAToPython intelligently suggests the best Python library for the job:
- pandasfor data manipulation and analysis.
- xlwingsfor automating Excel via the API.
- openpyxlfor reading/writing .xlsx files.
Deterministic Output: Why "No AI" Matters
If you work in Finance, Payroll, or Accounting, you cannot afford "hallucinations." Generative AI tools (like ChatGPT) guess the logic, often inventing functions that don't exist or misinterpreting critical financial formulas.
VBAToPython uses a deterministic parser. This means `x + y` in VBA will alwaystranslate to the exact mathematical equivalent in Python. Our engine analyzes the Abstract Syntax Tree (AST) of your macro to ensure 100% logic fidelity.
Enterprise-Grade Security
We understand that your macros contain proprietary algorithms, salary data, or trade secrets. That is why we built VBAToPython with a privacy-first architecture.
Frequently Asked Questions
Can I convert an entire .xlsm workbook?
Yes, once exported. You can export your modules to .bas files and upload them in a single batch. Native .xlsm extraction is on our roadmap.
Do I need to know Python to use the output?
The output is standard Python 3 code. While basic Python knowledge helps, our tool adds "Explainer Comments" to the code, teaching you how the old VBA logic maps to the new Python syntax.
Is this tool free?
We offer a free Compatibility Audit to see if your file can be converted. Full code generation starts at just $12 for a Day Pass.
