# Append rows to a worksheet

> Call this API to append one or more rows after the last existing data row in a DingTalk Spreadsheet worksheet; the system automatically locates the last row with data and inserts new rows below.

Call this API to append one or more rows of data after the last existing record in a DingTalk Spreadsheet worksheet. The system automatically locates the last record that contains data and inserts the new rows immediately below it.

## API call description

* Automatically locates the last record that contains data in the worksheet and appends new rows below it.
* Supports appending multiple rows at once through the `values` two-dimensional array.
* If the worksheet is empty, data is written starting from the first record.
* Returns the cell range (in A1 notation) where the appended data resides.
* The number of columns in the appended data should match the number of columns in the existing worksheet data to ensure data alignment.
