FAQ

Q: Are the original VB.NET files altered in any way?

Your existing code is left completely intact. The new Java files are output to the new location that you specify.

Q: What is the conversion accuracy?

Our accuracy is very high, but there will be significant adjustments required for all but the simplest conversions. There are no direct equivalents for some aspects of VB.NET. Read the rest of the FAQ to get an idea of a few things that are not converted. VB to Java Converter is intended to reduce the amount of work you'll have to do to convert code to Java, but it is just the first step.

Q: Does VB to Java Converter convert VB6 projects to Java?

No - the most effective way to convert VB6 to Java is to first upgrade to VB.NET, and then use VB to Java Converter on the resulting VB code.

Q: How are VB.NET methods with optional parameters converted?

Vba

Overloaded methods are created and the 'Optional' keywords are removed. Missing arguments are replaced by the defaults specified by the original VB parameter list.

Q: Are VB.NET delegates converted?

Yes - try out our Free Edition to see the conversion details. We convert delegate declarations to interface declarations and references to delegate instances to lambdas.

Q: Are VB.NET ByRef parameters converted?

Yes - try out our Free Edition to see the conversion details. We substitute a wrapper type (using Java generics) for the parameter type and adjust all references to the parameter in the defining method and all calls to the method.

Q: What about .NET UI code?

The converter does not convert .NET UI types due to the lack of similarity between these types and Java UI types.

Q: What are the most common adjustments necessary after conversion?

  • VB to Java Converter converts only some .NET types to Java equivalents. The converter offers options to use your own custom replacements.
  • There are no simple equivalents to VB events in Java, so these must be refactored.
  • Since Java lacks a preprocessor, all code dependent on conditional compilation needs to be refactored so that the functionality can be achieved in other ways.
  • VB LINQ query syntax is not converted since this feature is not available in Java (but LINQ method syntax is partially converted).
  • VB 'Structure' is converted to Java 'class', since Java does not include value types. We add a 'clone' method to the Java class to try to reproduce the same behavior as .NET value types, but adjustments may still be required.
  • If the VB project did not have 'Option Strict On' set, then you'll likely have a number of cases where different types are compared with each other - the converter will sort out most cases, but some may need adjustment.
  • Although some On Error GoTo statements are converted, some elements of classic VB unstructured error handling (On Error Resume Next, On Error GoTo -1, etc.) are not converted. These statements are marked as a 'ToDo' task.
  • 'When' statements in 'Catch' blocks (which have no equivalent in Java) must be manually adjusted. These are commented out and combined with a warning comment.
  • VB nullable logic cannot be converted since the necessary null-value logic must be applied to every aspect of expressions containing the nullable variable or method call. The only aspect of nullable instances that is converted is the declared type - the corresponding Java wrapper type is used for nullable primitives (e.g., the Java wrapper type 'Integer' is used for VB Integer? or Nullable(Of Integer)).

Additional Resources

Before you begin

You might want to update incompatible APIs in your VBA code before you convertyour files. For files that have the status Supported exactly, you can proceedto Step 1: Convert your files.

Modify incompatible VBA APIs

For files that have the status Supported with workaround or Needsinvestigation, you can apply your workarounds and fixes after the conversionin Apps Script, but we recommend that you modify the VBA code that you’refamiliar with first, before you convert your files.

For each API marked as Supported with workaround or Needs investigation inthe compatibility report, we recommend the following:

  • If the function performed by the API isn’t critical to your VBA macro workingproperly, remove it from your VBA code. If it is, change your code toimplement a similar behavior with supported VBA APIs.
  • For APIs with the status Supported with workaround, if you can’t switch tosupported VBA APIs, leave your VBA APIs as is. After you convert to AppsScript, a known workaround for this API is recommended in the comments of theconverted Apps Script code.
  • If the issue is coming from an unimplemented language construct, rewrite your code to avoid usingthose constructs.

  • For APIs with the status Needs investigation, check if your code containsany of the following APIs:

    • Adodb.connection
    • CreateObject: This API is often used to connect to database andenterprise resource planning software.
    • Shell.execute
    • OleObject

    If yes, we recommend that you don’t convert the files these APIs belong toand investigate other options. These APIs tend to perform critical operationsfor a macro, like connecting to a database or accessing a local resource, andApps Script is generally not a good solution.

Step 1: Convert your files

  1. On your computer, open Google Drive.
  2. On the right side panel, click the Macro Converter add-on . If you don’t see the side panel, at thebottom right, click Show side panel .
  3. Click Add files and folders. The Macro Converter only recognizes Excel files.
  4. Choose the files or folders you want to convert and click Select. Selectfewer than 2,000 files at a time.
  5. To change where your converted files are saved, click Change destination folder , and select the folder you want. Otherwise, the files are saved in your MyDrive folder.
  6. Click Convert.
  7. When the conversion completes, click View results.

Step 2: Test your converted files

Run your Apps Script code

After you convert your files, test the Apps Script functions. Test the convertedfiles with the data you normally use with your Excel files. If possible, comparethe output of your converted Sheets files with the output of your original Excelfiles.

Test your triggers

If your files contain triggers like onOpen(), onEdit(), or onClick(), testyour triggers, too. Some VBA triggers won’t convert automatically and need to beaddressed in Apps Script. See Address common issues.

Review ReadMe files

If a ReadMe file was generated with your converted file, review the conversionissues listed within the ReadMe file.

  • If the issues might be problematic for cases you haven’t tested, apply therecommended changes to your code.
  • If you’ve tested all possible scenarios and everything works as intended, youprobably don’t need to make changes.

Step 3: Fix errors

If you run into errors while testing your files, see Fix errors in yourconverted code.

If the code runs without errors, but the result isn’t what you expected, openthe file’s ReadMe file. Review each section to help determine what’s causing theissue and apply the recommended fix.

After you fix errors, test the file again to make sure everything works asintended.
