SQL to YAML Notes

INSERT statements in SQL dumps and scripts are parsed into rows.
Each table in a dump can be written to a separate output file.
When writing SQL, INSERT or UPDATE/UPSERT using a multi-column key can be generated.
The output indent can be set (2 spaces by default).
Flow style ({ } / [ ]) can be enabled or disabled.
Dotted column names can be written back as nested YAML mappings.

Check the preview table, then adjust the source options and the output options.
Click Convert — the YAML output is written in seconds. Save the session if you want to run it again from the command line.
