When you click Add/import board on Placker overview page, you will be asked how to proceed. One of the options is to import from Excel or other Spreadsheet software.
You can also click more on the top right corner and select import/update cards to add cards from a spreadsheet to an existing board.
The first step is to paste the spreadsheet content and select the destination board:
It is recommended to use the Placker default titles so they will be recognized automatically when you import (for example, use "List" as a column title, and not "Group"). However, if they are different, this can also be manually picked later.
Avoid using line breaks in Excel cells, as this could cause the import not to work
Then, set the format of date, number, effort and other attribute types. Make sure to have the correct date format, so it will be added correctly to your Placker board.
Also, you can use the "Include time" option in case you also wish to add this, or leave it unchecked if you're only adding dates.
Next step is to match the name of the columns on your spreadsheet to the existing attributes on your placker board.
You can include both custom and regular attributes. In all cases, at least the "Title" attribute must be added, so make sure one of your columns will be the title of the cards, as this is the only mandatory field.
The Placker attribute for due dates in "End date (Plan)". If this attribute is not visible in the dropdown options, it's probably because Placker didn't recognize the dates column (you will see "Pre-defined string" instead of "Pre-defined date"). If this happens, double-check your excel file to see if there are cells in a different format or is the date format options in step 2 are correct.
And that's it! In case any attribute was not imported correctly, review the formats to ensure they are in a compatible structure.
