A typical data operation
Most data jobs follow the same path from a messy export to something you can use. Each step has a tool here, and each tool's page explains exactly how it treats your data.
- 1
Inspect
Open the export as a table, exactly as a parser reads it, to check columns, IDs, and malformed rows before anything else.
- 2
Clean
Remove duplicate rows, fix values in specific columns, and rename, split, or normalize columns.
- 3
Query
Load files as SQLite tables to join them, aggregate, or filter with real SQL - or filter interactively.
- 4
Deliver
Convert the result into the format the next system needs: JSON, Excel, SQL inserts, or a Markdown table.
