Output CSV File

2 VersionsOutput

Writes each Analytics.TabularDataset to a fresh character-separated file named from a template plus a zero-padded index, with a configurable single-char separator, persisting a stream of typed tables to disk.

How it fits

Typical backends

A spreadsheet read by input_xlsx_file is round-tripped out as a character-separated file.

An existing CSV is re-read by input_csv_file and re-written, for example to change the field separator to a tab.

Caveats

Hard constraintdelimiter must be a single character; the two-character backslash-t YAML sequence is unescaped to a real tab at startup, and an empty or multi-character value falls back to a comma.
I/O contractLeading dots are stripped from file_extension, and an empty extension produces files with no suffix; cell quoting follows RFC 4180, wrapping cells that contain the separator, a quote, or a line break and doubling embedded quotes, with no other escape handling.
State lifetimeThe file index is process-local and starts at zero, so a redeploy resets it and reusing the same directory overwrites files unless name_template also varies.
State lifetimeAll configuration is captured once at first use; runtime changes have no effect.
