Data streaming is the continuous flow of data generated by various sources. In LibreOffice Calc, data streams can be processed, stored, analyzed, and acted upon as it's generated in real-time.

Some real-life examples of streaming data include use cases in every industry, including real-time stock trades, up-to-the-minute retail inventory management, social media feeds, multiplayer game interactions, and ride-sharing apps.

## Source stream

### URL

URL of the source document in the local file system or internet.

### Interpret stream data as

- value1,value2,...,valueN, and fill into range:

- address,value:

### Empty lines trigger UI refresh

## When new data arrives

There are three features of this option:

- Move existing data down: the existing data is moved down in index and the empty space is filled by arriving data. In short, we deal in fix range of indexes.

- Move the range down: the arriving data is appended at the end of existing data and range of indexes to be processed is shifted.

- Overwrite existing data: the arriving data overrides the existing data.

## Maximal Amount of Rows

Limit the maximum numbers of rows to a specified value or leave undefined, but limited to the LibreOffice Calc row limit.
