In fact you can use `.json` and `.xml`, just change the `ConvertFrom-Csv` to `ConvertFromJson` and `ConvertFrom-Xml` respectively.\n\n## Notes\n\nWhy not just use `Compare-Object`?\n- Searches using hashtable keys should be faster than `Compare-Object`. When working with many thousands or millions of records, the difference will be significant\n- Hashtables build a meta object which can be used to store metadata, e.g. object keys.\n- `Compare-Object` is generally unintuitive at least to the author. `.SideIndicator` grouping is difficult to manage and debug.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftheohbrothers%2Fget-duplicatecontact","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftheohbrothers%2Fget-duplicatecontact","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftheohbrothers%2Fget-duplicatecontact/lists"}
