+When creating the spreadsheet, you are required to have a column that contains a sample identifier. The identifier is case-sensitive and can contain either the sample names or IDs. When importing metadata from a **project**, the sample identifier can be either the **sample name or ID**. If importing metadata from a **group**, the sample identifier must be the **sample ID**.
 
 **An important note:** When importing a metadata spreadsheet, you will be asked if you'd like to **Ignore empty values**. If this is **selected**, any metadata fields without an associated value will be ignored and those metadata keys will not be removed from the sample if present. However, if this **not selected**, any samples with the metadata key and empty value will be **deleted**.
