Data Frame Creator

ivy.node.data-frame-creator · v0.0.0

ivyx✓

Creates a pandas DataFrame from a list of dictionaries. This is typically the starting point for data processing pipelines. Each dictionary in the list becomes a row in the DataFrame, with dictionary keys becoming column names. Use this node to convert structured data (e.g., from web-scraping or API responses) into a DataFrame for analysis. The output can be used with csv-from-data-frame for export or other data transformation nodes.
