Does anyone know why the max text lengt in power bi is 32 766 instead of 268,435,456 like the documentation says

documentation : https://docs.microsoft.com/en-us/power-bi/desktop-data-types#text-type

Hi @michieldeferm ,

There is a limitation of Power Query "M" and the Desktop data model types. In other words, the data model Text type can theoretically support large amounts of text but the import process using Power Query is truncating it to 32,766 characters.

While it is can be worked around with some clever M – you need to split long text values up into multiple smaller values stored in different columns or rows.

You can refer to the link:https://blog.crossjoin.co.uk/2019/05/17/maximum-length-text-value-power-bi/.

If you still have this issue for Power BI, you'd better create a support ticket in Power BI Support to get further help.

Best Regards,

Amy
