# Filtering Data in Excel Document
# Filtering Data in Excel Worksheet

Using [AutoFilters](https://support.office.com/en-US/article/Filter-data-in-a-range-or-table-01832226-31b5-4568-8806-38c37dcc180e), data can be filtered to enable quick and easy way to find and work with a subset of data in a range of cells. When the data is filtered, entire rows are hidden if values in one or more columns does not meet the filtering criteria. The following are the types of filters that can be used in XlsIO.
Using AutoFilters, data can be filtered to provide a quick and easy way to find and work with a subset of data in a range of cells. When the data is filtered, entire rows are hidden if values in one or more columns do not meet the filtering criteria. The following types of filters are available in XlsIO through the [IAutoFilter](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html) interface:

* Custom Filter (Conditional)
* Combination Filter (Text and DateTime filter)
* Dynamic Filter
* Color Filter
* Icon Filter
* Advanced Filter
* [Custom Filter (Conditional)](#custom-filter) using [ExcelFilterCondition](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.ExcelFilterCondition.html)

## Applying Filter
N> The column index used in `worksheet.AutoFilters[index]` is **zero-based** and is relative to the `FilterRange`. The first column of the filter range is index `0`.

The following code example illustrates how to apply simple auto filters.
## Applying Top10 Filter

The following code example illustrates how to apply a [Top10](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_IsTop) auto filter that retains the top N cells of a column. To apply a Top10 filter, the [IsTop](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_IsTop) and [IsTop10](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_IsTop10) properties must be set to `true`, and [Top10Number](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_Top10Number) must be set to the number of cells to keep.

## Combination Filter

This filter contains both Text filter and DateTime filter. It filters the data based on multiple criteria.
A combination filter combines text and date/time filters to filter data on multiple criteria in a single column. Use [AddTextFilter](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_AddTextFilter_System_String___) to add text values and [AddDateFilter](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IAutoFilter.html#Syncfusion_XlsIO_IAutoFilter_AddDateFilter_System_DateTime_Syncfusion_XlsIO_DateTimeGroupingType_) to add date values; the available [DateTimeGroupingType](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.DateTimeGroupingType.html) values are `Year`, `Month`, `Day`, `Hour`, `Minute`, and `Second`.

## Advanced Filter

Advanced Filter can be used to perform more complex filtering other than basic filters. Data can be filtered with custom defined criteria range.

Advanced Filter support two types of filter action.
The advanced filter can be used to perform more complex filtering beyond basic filters. Data can be filtered with a custom-defined criteria range.

1. Filter in Place
2. Filter Copy
The advanced filter supports two types of [ExcelFilterAction](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.ExcelFilterAction.html):

**Filter in Place**: Filter data in same location.
**Filter Copy**: Filter and copy data into new location within a worksheet.
1. `FilterInPlace`: Filter data in the same location.
2. `FilterCopy`: Filter and copy data into a new location within a worksheet.

Advanced Filter also provides an option to filter the unique records. This will remove the duplicate record from filtered data.
The advanced filter also provides an option to filter only the unique records, which removes duplicates from the filtered data. Pass `true` as the last argument of [AdvancedFilter](https://help.syncfusion.com/cr/document-processing/Syncfusion.XlsIO.IWorksheet.html#Syncfusion_XlsIO_IWorksheet_AdvancedFilter_Syncfusion_XlsIO_ExcelFilterAction_Syncfusion_XlsIO_IRange_Syncfusion_XlsIO_IRange_Syncfusion_XlsIO_IRange_System_Boolean_) to enable unique-record filtering.
