File Format Specifications

In order to ensure that the best-possible output is achieved, it is critical that the input file be received in the proper format.

Please note that following our file format specifications is required only for our Self-Service clients. For those using our Full-Service, Automated and Enterprise services, please know that proper formatting will be confirmed and/or implemented by our expert Data Specialists.

Input File Format

Cleanlist's automated list processing systems require you to submit data in the following format. If you are unable to submit your data in this format, please consider upgrading to our Custom Projects delivery option and our data specialists will convert your file for you before processing.

Submitted files must be compressed in ZIP format. Please include only one file per order.

File Types

• Fixed Length ASCII Text
• Tab, Pipe or Comma Delimited ASCII Text
• If commas are used, field values must be enclosed in quotes.

Encoding

• WIN-1252 (Windows)
• CP-437 (DOS)
• Lines are terminated with either CRLF or LF

Input Fields

All of the fields below must be allocated in the input file, although naturally some values may be blank. In the case of fixed-length files, the field lengths should all correspond to the maximums below.

Output File Format

Your output file and service reports will be bundled together and delivered in ZIP format.

Your updated contact list will contain your input data (unchanged) with replacement data appended into new columns to the right. The fields appended vary depending on the services you order and are described in the File Layout portion of your report, which is provided with each completed order. Refer to individual service descriptions in the Solutions section of this web site for a detailed description of the fields provided.

Output files are delivered in the same format as they were submitted to Cleanlist.
