Is There an Excel VBA Converter? Every Tool Checked, and What They Miss

TL;DR: As of late 2026 we found one vendor-supported converter aimed at a mainstream destination: Google's Macro Converter, which turns Excel VBA into Google Apps Script for Workspace Enterprise Plus and Education Plus customers, and documents what it skips. Microsoft offers no VBA converter for Office Scripts or anything else, and its staff have said so on Microsoft Q&A. Nearly every other "VBA converter" is an AI prompt with a text box, a snippet-level rule-based tool, a small open-source project, a VB6-to-.NET product that does not read Excel VBA, or an Excel-to-web platform that drops the macros. None of them handle UserForms, workbook events, Outlook or Word automation, file system access or Windows API calls. Those parts are rewritten by hand, whichever route you take.

The search usually starts with a practical problem. The macros that run the month-end report do not work in Excel for the web, on a colleague's Mac, or in the browser-based tool the team is moving to. Somebody asks whether the VBA can just be converted. We went through every tool that answers yes.

Why Is There No Simple VBA Converter?

VBA is a small language attached to a very large object model. A macro is mostly calls into Excel itself, and into whatever else was on the Windows PC when it was written: Outlook, Word, the file system, ADO database connections, a dialog box that waits for the user. Translating the language is easy. Translating the environment is the job, and most of that environment does not exist in a browser, in Google Sheets or on a server. Microsoft's own comparison of Office Scripts and VBA puts it plainly: Office Scripts have access to the workbook, not the machine hosting it, do not support Excel-level events, and are not available in other Office products.

What Does Microsoft Offer?

Office Scripts, written by hand. Microsoft's replacement for VBA in the cloud is Office Scripts, in TypeScript, available on Microsoft 365 business, enterprise and education plans and only in preview for personal and family plans. There is no converter. The Office Scripts product team said in 2021 that none was offered and suggested the Action Recorder as a starting point, and a moderator on Microsoft Q&A repeated in October 2025 that there is no automated tool to convert VBA into Office Scripts. The scripts themselves run only when a user starts them or Power Automate calls them, cannot respond to workbook events, cannot show a form mid-script, and cannot reach the machine the workbook is on. We cover what that means for a macro-driven workbook in Excel VBA limitations online.

Copilot. Copilot will write or debug VBA in chat, and third-party reports describe it drafting Office Scripts from a description. Microsoft has not documented a feature that reads an existing macro and produces an Office Script, and nothing Copilot generates has been tested against your workbook. It is a way to write new automation, not a migration path for old automation.

Python in Excel is not a VBA replacement either: Microsoft states the Python code has no access to your computer, no network access, and can return only values or images, not macros.

Every Tool That Claims to Convert VBA

Tool	Converts VBA to	Who can use it	What it cannot handle, in its own words	Verdict
Google Macro Converter (Workspace add-on)	Google Apps Script, with the workbook moved to Google Sheets	Workspace Enterprise Plus and Education Plus only	Does not convert UserForms. BeforeSave has no workaround. ADODB, CreateObject, Shell and OLE objects are flagged for investigation. Unsupported calls become stubs that throw.	The only real converter. Rated 2.4 out of 5 by 222 Marketplace reviewers.
Office Scripts (Microsoft)	Nothing automatically; you rewrite in TypeScript	Business and education Microsoft 365 plans	No events, no forms mid-script, workbook-only access, no other Office apps, external calls restricted.	A destination, not a converter.
Snippet converters (VBAtoPython.com, CodeConvert, Taskade and similar)	Python or JavaScript, one snippet at a time	Anyone, free tiers with limits	VBAtoPython.com is rule-based rather than AI, says about 60% of its output is production-ready, and lists UserForms, PivotTables, ActiveX, Win32 API calls and external COM objects such as Outlook and Word as out of scope or manual work. The AI sites publish no accuracy figures.	A first draft of the language layer.
Open-source projects (vba2py, a 2018 VBA-to-JavaScript translator, xlsliberator)	Python, JavaScript, Python-UNO for LibreOffice	Anyone	vba2py excludes COM, UserForms, ActiveX, Windows API declarations, Application calls and events in its first version. The JavaScript translator says it will not perform a complete translation and was last updated in 2018.	Experiments, not products.
VB6 migration products (VBUC, VB Migration Partner, Instant C#)	VB.NET or C#	Companies with Visual Basic 6 applications	They do not take Excel VBA at all; the input is a VB6 or VB.NET project.	The wrong product, often found by the right search.
Excel-to-web platforms (SpreadsheetWEB, Sheetcast, Coherent Spark)	Nothing; the macros are dropped	Subscribers	SpreadsheetWEB's FAQ recommends saving as .xlsx first and its current platform runs the workbook as though macros were switched off. Sheetcast: "does not support the use of VBA". Spark does not convert macros.	Fine for formula-only workbooks.
VBA runtimes (LibreOffice VBASupport, the elixcee interpreter)	Nothing; they run a subset of VBA without Excel	Anyone	LibreOffice offers limited support and says you may have to edit the code. elixcee targets data-processing macros and skips dialogs and screen updates.	Useful for batch jobs, not for a web app.

The pattern is the same in every row. The parts of VBA that are just a language convert. The parts that reach out of the workbook do not, and in a real business macro those parts are the point: the form the user fills in, the event that fires on save, the email that goes out, the file that gets written.

How Does the One Real Converter Work?

Google's Macro Converter is worth understanding because it shows what a serious attempt looks like. Before converting, it produces a compatibility report that sorts each file into three groups: supported exactly, supported with workarounds, or needs more investigation. Google publishes the list of roughly 800 VBA calls it can translate, recommends fixing the VBA and re-running the report before converting, and writes a stub for anything it cannot translate so the failure is visible rather than silent. Even with that machinery, UserForms are recreated by hand, keyboard shortcuts are re-added by hand, and files that depend on database connections or local system access may not be worth converting at all. It is also only available on the Enterprise Plus and Education Plus editions, and the destination is Google Sheets, not a web app.

What None of the Tools Handle

• UserForms. The dialogs where people enter data. Google says to rebuild them manually; Office Scripts have no equivalent; the AI tools list them as manual work. Our guide to converting an Excel UserForm to an online app shows what they become instead.
• Events. Code that runs on open, on change, on save, on a timer. No converter produces an equivalent because the destinations do not have one.
• MsgBox and InputBox in the middle of a procedure. A script that pauses to ask the user something is a conversation, and the web equivalent is a screen, not a function call.
• Automation of other applications. Sending Outlook mail, filling a Word template, reading an Access database through ADO. These are rebuilt as server-side features.
• The file system, Shell and Windows API declarations. There is no C: drive in a browser.
• On Error and GoTo logic. It can be translated, but almost always needs restructuring so that errors are handled where they occur.

What Converting VBA Actually Involves

Because the hard parts are environment rather than language, converting a macro-driven workbook is a design job before it is a translation job. Each procedure is read for what it does, not how it does it: this one validates an order, that one produces the month-end PDF, this one emails the result. Then each becomes application code with the same inputs and outputs, in a web app where the UserForm is a screen, the save event is a save button or an automatic check, and the Outlook call is a server sending the email. The language-level translation is the mechanical part; we publish our construct-by-construct table in the VBA to JavaScript mapping reference and the overall approach in how we convert Excel VBA macros to JavaScript. Every result is then checked against the original workbook, which is the step no converter can do for you.

Which Route Fits Your Situation?

You want to	Realistic route
Move to Google Sheets, you are on Workspace Enterprise Plus, and the macros process data rather than drive forms	Google's Macro Converter: run the compatibility report first, then plan hand work for anything it flags.
Stay in Microsoft 365 and run the automation in the cloud	Rewrite the macro as an Office Script by hand, accepting that forms, events and external calls need a different design.
Keep a formula-only workbook and just publish it	An Excel-to-web converter; we compare them in the converter roundup. Save the file as .xlsx first, since the macros will not come along.
Let a team or customers use the macro-driven tool in a browser, on any device	A custom rebuild: the VBA becomes application code, the forms become screens, the output is source code you own.

For the last row, a workbook with VBA and user accounts typically sits in the $3,000 to $5,000 and up tier and takes 3 to 6 weeks, with the price fixed before work starts. The VBA conversion page walks through what each construct becomes and shows recent macro-driven conversions. Or send us the workbook: the free Conversion Blueprint lists every procedure, what it turns into, and a fixed price, within 24 hours.

Frequently Asked Questions

Is there a tool that converts Excel VBA automatically?

One that matters, with limits. Google's Macro Converter add-on translates Excel VBA to Google Apps Script for Google Workspace Enterprise Plus and Education Plus customers. It produces a compatibility report, does not convert UserForms, and turns unsupported calls into stubs that throw an error. Microsoft does not offer a VBA converter for Office Scripts or anything else, and the other tools that use the name are AI prompts, small open-source projects, or VB6 migration products that do not take Excel VBA.

Can Microsoft Copilot convert VBA to Office Scripts?

Not as a documented feature. Copilot can write or debug VBA in chat, and third-party reports describe it drafting Office Scripts from a plain-language description, but Microsoft has not shipped or documented a tool that reads an existing macro and produces an Office Script. A moderator on Microsoft Q&A confirmed in October 2025 that no automated VBA-to-Office-Scripts tool exists. Anything Copilot produces has to be tested against the original workbook.

Does Google's Macro Converter handle UserForms, events and database connections?

No. Google's documentation says the converter does not convert UserForms and they must be recreated manually in Apps Script. BeforeSave has no workaround because Sheets saves automatically. Calls such as ADODB connections, CreateObject, Shell and OLE objects are flagged as needing investigation, and Google notes that converting files that rely on them may not be recommended.

Can ChatGPT or Claude convert VBA to JavaScript?

They can translate a procedure, and for a short, self-contained macro the output is often close. There is no published benchmark for VBA translation accuracy, and the models cannot see the workbook the macro runs against. Treat the output as a first draft that still needs the dependency mapping, the user interface and the side-by-side verification a developer would do.

Which Excel-to-web tools can run my VBA?

None of the converters convert it. SpreadsheetWEB recommends saving the file as .xlsx before upload, which strips the macros. Sheetcast states it does not support VBA. Coherent Spark does not convert macros. EASA says it retains VBA, which it achieves by running the workbook rather than converting it. For a web app that behaves like the macro-driven workbook, the VBA is rewritten as application code and verified against the original.
