Hi,

If you're getting errors about multiple tags for the same record when importing a CSV or XLSX file into Odoo, it typically means that there are multiple rows in your file that represent the same record, but with different values for some fields. This can happen if you have duplicate rows in your file, or if you have rows with the same unique identifier (e.g. a client ID), but different values for other fields.

To resolve this issue, you'll need to clean up your data file to ensure that each record is represented by a single row with consistent values for all fields. Here are a few steps you can take to do this:

1. Remove duplicates: Use a tool like Excel's Remove Duplicates function to remove any duplicate rows in your file.

2. Consolidate data: If you have multiple rows for the same record with different values for some fields, you'll need to consolidate this data into a single row. One way to do this is to sort your data by the unique identifier (e.g. client ID), and then manually review the data to ensure that each record is represented by a single row with consistent values for all fields.

3. Use a data cleaning tool: If you have a large data file with many inconsistencies, it may be helpful to use a data cleaning tool like OpenRefine or Trifacta to clean up your data and ensure that each record is represented by a single row with consistent values for all fields.

Once you've cleaned up your data file, you can try importing it into Odoo again. If you're still getting errors, check the import logs to see if there are any specific records or fields that are causing issues. You may need to make further adjustments to your data file to ensure that it conforms to the format expected by Odoo's import function.
