Just a question, will there be any data loss if a field with number type is converted to a text type? I've read from Salesforce help documentation that changing to Number from any other type can cause data loss. But how about vice versa?
As per the documentation there is no mention of data loss when you change the type from number to text.
So this type of conversion shouldn't cause any data loss. Also a number can have numbers and decimal character. Which the text field will also have,i.e. a text field can have alphanumeric and special characters both. So there seems no scope of data loss in this case.
You can give this a try yourself in some dev org.
