std.csv

Quotes field (doubling embedded quotes) when it contains a comma, quote, or newline; returns it unchanged otherwise.

• field: Field text to quote if it needs it.

println(std.csv.escape_field("moon, language")) // "moon, language"
println(std.csv.to_row(["moon", "language,tour"]))
println(std.csv.parse_row("moon,\"language,tour\""))

Splits one record into fields: commas separate, "..." quotes protect separators, "" inside quotes is a literal quote, bare \r outside quotes is dropped.

• line: One record, without its terminating newline.

One record: fields joined by commas, each escaped like escape_field.

• fields: Field values for one record, in column order.

Parses a whole document into records of fields. Records split on newlines outside quotes; empty records are dropped.

• text: A whole document; records split on newlines outside quotes.

let rows = std.csv.parse_csv("name,year\nmoon,2026")
println(std.csv.row_count(rows))
println(std.csv.col_count(rows))
println(std.csv.get_column(rows, 0))
println(std.csv.to_csv(rows))

Rows joined by \n, each rendered like to_row. No trailing newline.

• rows: Records to render, each a list of field values.

Column col from each row that has it (rows too short are skipped).

• rows: Records to read down.
• col: Zero-based column index; rows too short are skipped.

The number of records.
