Practical tool guides

Work through common data conversion, API debugging and cleanup tasks with examples and linked tools.

Convert nested JSON to CSV without losing fields

Choose between flattened columns and JSON cells, preserve arrays and review missing values before exporting.

Capture one request as cURL, convert it to requests or fetch, and review credentials and browser restrictions.

Remove duplicate lines, choose matching rules and join wrapped text without accidentally sorting your list.

Validate records, preserve identifiers, choose NULL behavior and inspect generated SQL before importing.

Compare random and time-based identifiers, encoded timestamps and the limits of chronological sorting.
