1. A method for compression of data, comprising:
accessing tabulated data in at least two of a plurality of first file formats, wherein the at least two of a plurality of first file formats are incompatible with one another;
extracting attributes from the tabulated data;
dividing the tabulated data into chunks;
processing the extracted attributes and chunks into correlated information;
storing global data for compressors shared across chunks; and
generating a file in a second file format that includes the correlated information, and further includes information indicative of the different compressors being used to compress the chunks and attributes,
wherein the second file format is different from the first file formats,
wherein the correlated information includes a two-dimensional array of cells, and
wherein the two-dimensional array of cells includes a first row containing column attributes and a second row containing row attributes.
