Title says all.

I was told your Java scrip could/should convert the Microsoft Education edition because it has the same level structure as PE (or so I am told from MinecraftWorldMap.com).

I'm willing to pay $200 if you create a converter that converts LevelDB (Windows 10 edition) maps to Anvil (Java edition) that are newer than 1.2.13 update (that use a new format).

If interested, please reply with your Discord name so we can discuss this there.

Hi there, I get quite a few unknown keys like the one below (not sure if this is a problem) but the iterator eventually runs into the fatal exception below.
cheers,
Phil

"Worldanvil" folder is empty after convertation

I wanted to convert an older world (older than v 1.0 pe) so I downloaded v1.0, but there was no start.bat in it, or really anything else other than a readme and the src. Help?

I click the start file and i see a black box appear for a millisecond then it disappears and nothing happens. In a tutorial I watched it says files should appear in world anvil file however nothing changes. I have put in a zip file containing these files and my world so please contact me.
LevelDb2Anvil-master.zip

When using this tool on windows 7 to import a leveldb world from MCPE 0.10.5 to convert it into anvil . When starting the batch file we can see "done !" message on the Command Prompt but there is no folder generated or files from this conversion.

Update : When using last commit I get this error :

Where do I upload my world file?
there's no instructions other then
"Import your LevelDB world in..."
In where?

When I try to convert a world, this happens:

This is most likely due to some changes which were officially made here:

https://github.com/Mojang/leveldb-mcpe

When I try to Start the program a window opens for a split second then closes and the log.txt says " 'java' is not recognized as an internal or external command, operable program or batch file." Do I need to get something to run the program or does it just not work currently?

I left the folder named as downloaded: "/LevelDb2Avnil-2.1". The converter process stops on an error stating the file Converter.jar could not be opened. When I renamed the folder with no "." (period), the converter worked. I am working in Ubuntu 16.04.

Its Not coverting For me.

I know this has been said before, but I click the start.bat file and it shows the little cmd windows for a few secs, then closes and nothing happens. I have put my world file into it, renamed it to 'world,' and stuff but is there something else I need to do, like install java or something (I may already have java, IDK) but any help would be appreciated. I have gone to the point of manually rebuilding a map block for block because this didn't work. Please help!

When trying to run the converter, I get this error:

the title says it all. I will show you the error later. Some thing about gzip?

Whenever I run the Anvil to LevelDB script, I get this error:

aj@aj-ugnome:~/dev/MConverterUltimate-master/Anvil to LevelDB$ ./start.sh
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on
Failed to check folder "world" 's validation. Problem: world is not a valid Anvil folder


Map converter for Minecraft:Pocket Edition, from format "LevelDB" to "Anvil", or from format "Anvil" to "LevelDB". (c) ljyloo 2015

Usage:
    java -jar Converter.jar <import folder> <export folder> <type>
Where:
    <import folder> The full path to the folder containing Minecraft:Pocket Edition world
    <export folder> The full path to the folder which you want to export
    <type>  0 represents "LevelDB" to "Anvil", 1 represents "Anvil" to "LevelDB"
Example:
    java -jar Converter.jar /home/ljyloo/LevelDB /home/ljyloo/Anvil 0

My 'world' is an exported world from WorldPainter that opens fine in Minecraft 1.8. What am I doing wrong?

Some blocks were incorrectly converted:
Grass Path became the Ender Rod (and Ender rod in MCPE became Grass Path in PC after convertation):


Quartz slab became Nether brick slab:


Oak slab became Dropper:

When ever I try to run the program it always says the the import folder doesn't exist. I know for sure that the folder DOES exist and that my path is correct! What am I doing wrong?

I'm just starting out in programming, so I'm illiterate when it comes to this.. I understand the java -jar Converter.jar it's just the folders that are really kicking me. I put the LevelDBtoAnbil folder in the root (because I thought maybe I did something wrong?) but I'm not really sure what I'm doing. Please help, much is appreciated!

for some reason whenever i start the batch file the command shows up for a second and the files are not there

I think it will be very cool to do support for the "mixed" worlds, with chunks created by mcpe 0.9 - 0.16 and mcpe 1.0+, because I have world created a long time ago with Minecraft PE 0.9.5, and I still play on it. Now I use MCPE 1.0.0.16, and latest version of converter converts only chunks edited with PE 1.0.0.16, but I want to convert a whole world!

Have to use Legacy Java 6 because java command line doesn't work with Java 8.

the link brings you to a video on converting a PC/Java world to a PE/Windows 10 world

For some reason, my world isn't exported. No error messages appear. Just a "done." message.

root@pm:~# java -jar Converter.jar /home/dannyg/DG /home/dannyg/s2/worlds/DG
Done!
