To edit ATV file, we strongly recommend installing software that works with ATV files. Of course, there are probably ATV Online Editors available, but none of them will be able to provide such a wide range of available options as dedicated software.
Please note that not every program that supports ATV will allow you to edit the file. If you want, you can learn more about the ATV file extension.
Definitely the best solution. Use any of the programs that support the ATV file to check if it allows you to edit the file. It's safest to download the software from the developer's website. You can find direct links to the creators' websites on the subpages of each application. Below you will find some examples of software programs that support the ATV file (so it is very possible that they can edit files in ATV format).
And here is the full list of programs supporting the ATV file
Most of the file formats are simply text format saved under a different extension - so you can open them e.g. with Windows Notepad But beware - making manual changes to the ATV file or another may result in its damage. When you save the changes, you may no longer open the ATV file. By far the safest way is to use file editing programs that works with the ATV extension.
It seems that one of the software on the list must be able to edit the ATV files. Use other options if you still haven't found a way to edit ATV. Below are tools that allow you to edit ATV online files.
