Grey lines inside grid lines

[greshoff]

Hi

I have some lines inside the grid lines on some of the cells on my spreadsheet.  What are they and

how do I remove them just leaving the grid lines?

Many thanks

Have you probably pasted data from another source into that spreadsheet?

You can delete these borders by going to the Home tab of the ribbon > Borders > No border

Alternatively, select a cell without any format, click on the Format Painter on the left of the attached image above and then select the cells with these greyed borders in order to apply the former selected format and delete these borders.
