In September 2016, the Z1 Financial Accounts website will be streamlined. A single Z.1 PDF file and a single set of compressed CSV files will replace current PDF, CSV, and PRN files. The new PDF file will show series mnemonics along with recent annual and quarterly data. The new compressed CSV files will have series mnemonics and all historical data. HTML tables and Data Download Program data, including underlying detail, will remain unchanged. A preview of the new PDF and CSV files, using June Z.1 data, is available on the Z1 homepage at: www.federalreserve.gov/releases/Z1/
