Load Data with COPY

I have 7,000+ rows of data in Numbers. Exported to .csv file, tried to
load into postgres table with COPY FROM, failed. Postgres does not
recognize the format:

ERROR:  invalid input syntax for integer: "project_name,...

Is there any way to export/convert the data in Numbers into a format
recognizable by postgres?
Mac OS 10.10.6; postgres 9.3.5.2

Please, advise. Thank you,

Diana
