Check structure before conversion
CSV and TSV represent tables, while JSON, YAML, and XML can carry different nested structures. Check headers, delimiters, arrays, and objects before converting, then sample important fields.
Validation, table viewing, flattening, and deep merging solve different tasks. Configuration formats also support different value types, so verify converted settings in the target application.
Before you choose a tool
- Review numbers, booleans, nulls, and strings after conversion.
- Choose the intended Excel worksheet; CSV does not preserve spreadsheet styling.
- Processing is local to the browser, but large files still consume device memory.
