+## Reading Specific Columns (Column Filtering)
+
+By default, Fesod reads all columns from a sheet. If you only want to process
specific columns, you can use `.includeColumnIndexes(List<Integer>)`. This
selects specific columns out of the entire sheet column set
+
+### Reading Specific Columns to Map List (Synchronous)
+
+When reading without a POJO template, the filtered columns are packed
sequentially into the resulting `Map<Integer, String>`. The first targeted
column is mapped to key `0`, the second to key `1`, and so on.
+
+```java
+@Test
+public void readSpecificColumnsToMapList() {
+ String fileName = "path/to/demo.xlsx";
+
+ // We only want to read Column A (Index 0) and Column C (Index 2)
+ List<Integer> targetColumns = Arrays.asList(0, 2);
+
+ List<Map<Integer, String>> list = FesodSheet.read(fileName)
+ .sheet()
+ .includeColumnIndexes(targetColumns)
+ .doReadSync();
+
+ for (Map<Integer, String> data : list) {
+ // Column Index 0 is mapped to key 0
+ String id = data.get(0);
+ // Column Index 2 is mapped sequentially to key 1
+ String age = data.get(1);
+
+ log.info("ID: {}, Age: {}", id, age);
+ }
+}
+
