Depending on the file format, you will have different options to choose from to create assets.

Create assets for CSV upload

When uploading a CSV file, you have the option of selecting the delimiter used in the file. This will define how your assets will be created.

You will have the option of defining an input type, which can help improve the way Lettria analyzes your text.

Create assets for Text and PDF upload

When uploading a Text or PDF file, you have the option of choosing whether you want the entire document to be one single asset, or whether you want to separate assets by line breaks.

Select input type

Finally, click 'Create' to create your dataset.
