Hi,

This error happens because Odoo is trying to parse the date using the format you specified (%d/%m/%Y), but the actual date in the file is already in the format YYYY-MM-DD (1995-01-01), which doesn't match.

solution:

1. Adjust the date format in Excel to match odoo import format

Select the date column in Excel. Format -> Number -> Custom date and time

set custom date as (%d/%m/%Y)

2. Adjust the date format in Odoo to match in Excel

Setting -> Translations->Language

Select your language and change the date format.

Hope it helps
