# Excel cell metadata and formatting in Parse

> Advanced Excel parsing can preserve source cell references, formulas, and structured cell formatting in parse output.

Advanced Excel parsing can now preserve source-cell provenance and formatting in parse output.

* Set **`advancedOptions.excelIncludeCellMetadata`** to return source cell references such as `B2` or merged ranges such as `A1:C1`; formula cells also include the source formula text.
* Set **`advancedOptions.excelIncludeCellFormatting`** to return structured cell formatting such as bold, italic, font color, and background color.
* For HTML table output, metadata is also emitted as `data-cell` and `data-formula` attributes, and formatting preserves inline cell styles.

Both options are off by default and require `advancedOptions.excelParsingMode: "advanced"`. See the [Parse configuration guide](/parsing/configuration) for setup details.
