Will xmlDocument.Load be overloaded if the input xml is over 100MB?

We are using a tool that takes an XML file as input and converts it to CSV. The tool is working fine for a 50MB file, but throwing an exception for a 100MB file.

After analysis I found that the xmlDocument.Load function is overloaded with the input. Can you please suggest any way to deal with the errors?

The XmlDocument loads the whole document to memory and builds a DOM tree of it. Thus, it throws OutOfMemoryException for large files.

Instead you could use the XmlTextReader which reads the document token-by-token. It requires some code to handle the structure of the XML data but using this approach you can read arbitrarily large documents without issues.
