Convert a CSV to any of 33 formats.

One export sheet for every format: choose the rows, the columns and their order, and the options the format needs — then save the combination as a preset for next time.

The export sheet

  1. Open the file and press ⌘E.
  2. Choose the format — or one of your saved formats.
  3. Choose the rows: all, only those the filter shows, or only the selected ones — with a row limit if you like.
  4. Choose the columns, tick or untick them, and drag them into the order the receiver wants. The choice is kept for the file, so the next export starts where this one left off.
  5. Set the format's options and save. A preview shows the first rows as they will come out.

Options that come up often

  • Empty values: leave them empty, or write NULL, a dash or anything else.
  • Decimal separators: keep them as written, or normalise every number to a point or a comma.
  • Column names: include them or not.
  • Encoding and BOM for text formats; sheet name for workbooks; table name and rows per INSERT for SQL.

Presets and automation

Save any combination as a named format in Settings ▸ Formats; ten are built in, including Excel (European), Excel (US), RFC 4180 and a PDF report. For conversions that happen every day, AppleScript can do it without the sheet: export table to "~/Desktop/sales.xlsx" — the ending picks the format.
