Removing Other Invisible Invalid Characters

If the metadata validator is throwing invalid character errors but there aren't any visible in the spreadsheet, follow these instructions: 

1. Copy data
2. Paste into google sheets
3. Download as .tsv
4. Open in excel
5. Save as .txt (tab delimited)
6. Validate

Another way to remove Invisible characters:

1. Press Ctrl+F to display the Find tab of the Find and Replace dialog box.
2. In the Find What box, hold down the Alt key as you type 0010 on the numeric keypad. It may not look like anything is in the Find What box, but the character is there.
3. Click Replace All.
