When should I use DLT (Data Load Tool) instead of Google Sheets ETL?

Building self-normalizing, schema-inferring data pipelines from REST APIs to warehouses with minimal code. Loading from SaaS sources and databases into Snowflake, BigQuery, or DuckDB automatically. Teams wanting declarative pipeline definitions without adopting a full orchestration framework

When should I use Google Sheets ETL instead of DLT (Data Load Tool)?

Syncing data from Google Sheets into a data warehouse for teams using Sheets as a data source. Business teams who maintain reference data or manual inputs in Sheets that feed into pipelines. Low-code integration between spreadsheet data and downstream analytics without custom scripting

What are the main weaknesses of DLT (Data Load Tool)?

Newer tool with a smaller community and fewer connectors than Airbyte or Fivetran. Less suited for complex multi-step transformations; pair with dbt for the transform layer. Limited support for real-time or streaming ingestion scenarios

What are the main weaknesses of Google Sheets ETL?

Google Sheets has row and cell limits that make it unsuitable as a data source for large datasets. Data quality in Sheets is often inconsistent; requires validation before warehouse loading. Not a general-purpose ETL tool — narrowly scoped to Google Sheets as the source

How Python Data Engineers Use These Tools

DLT (Data Load Tool)

Python data engineers use dlt to replace hand-written ingestion scripts. You decorate a Python generator function as a `@dlt.source`, define resources with `@dlt.resource`, and call `pipeline.run()` — dlt handles schema creation, type casting, incremental state, and writing to your destination warehouse automatically.

Google Sheets ETL

Python data engineers use the `gspread` library to read business-owned datasets from Google Sheets into pandas DataFrames for pipeline processing. A common pattern is a weekly data feed maintained by a business team in Sheets — Python reads the latest values, validates them with Pydantic, transforms them, and loads them into the warehouse alongside operational data.
