# Tab Delimited Empty Cells

By default, when filtering spreadsheet files, KeyView skips over empty cells. This behavior removes unnecessary tab characters from the output, but it also loses the table structure. If you require the table structure, you can configure KeyView to ensure that tabs exist between empty cells.

To enable tab delimiters around empty cells

- In `formats.ini`, set the `TabDelimited` parameter to TRUE. For example:

      [Options]
      TabDelimited=TRUE
