When uploading a CSV file to import data into Salesforce using the Data Import Wizard or Data Loader, you may find that all columns appear merged into a single string. This prevents you from mapping columns or data to their respective Salesforce fields.
This problem is caused by the delimiter used when the spreadsheet was saved as a CSV file. In many European countries, regional settings in spreadsheet programs use a semicolon as the delimiter. However, Salesforce supports only comma-delimited CSV files. Follow the steps below to convert your spreadsheet into a comma-delimited CSV file.
