# Fixing Data in Fix & Maintain

Use Fix & Maintain to make corrections to source dimensions, harmonized dimensions, and data classification values. There are two ways to fix data. To make bulk changes, export exception reports manually, fix incorrect values, and then import the fixed data. To make a few changes, use in-line editing within Fix & Maintain and make changes directly in Marketing Cloud Intelligence.

- **[Fix Multiple Files Using Import and Export](https://help.salesforce.com/s/articleView?id=mktg.dato_harmonize_validate_fm_fixing_multiple.htm&release=264.0.0&type=5)**  
    Use import and export to fix multiple files when exceptions occur. There are two types of export options; export and download a file, or use schedule export to export the report at a set time and send to specific recipients.
- **[Fix Single File Using In-Line Edit](https://help.salesforce.com/s/articleView?id=mktg.dato_harmonize_validate_fm_fixing_single.htm&release=264.0.0&type=5)**  
    To fix an entity inside Fix & Maintain, use in-line editing. A list of your harmonized data, including harmonized dimensions, source dimensions, and data classifications appears in order of least successful harmonization to most successful.
- **[Modify Harmonized Dimension](https://help.salesforce.com/s/articleView?id=mktg.dato_harmonize_validate_fm_fixing_dim.htm&release=264.0.0&type=5)**  
    If after applying fixes to a harmonized dimension the setup changes by deleting a pattern or adding or removing a dimension, future fixes aren’t saved.
