Document Type and Number:
Japanese Patent JP5175284
Kind Code:
B2
Abstract:
A system is provided for processing spreadsheets to compress the storage of formulas in the spreadsheets. The system comprises a searching unit (101, 103) for searching each cell in the spreadsheet to determine whether each cell contains a formula; a first store for storing each unique formula; a second store for storing a unique identification for each unique formula in the first store; and a comparing unit comprising means (105) arranged to compare a formula contained within a cell and detected by the searching unit with the formulas stored in the first store, and means (107), if the detected formula is in the first store, for replacing each formula occurring within the spreadsheet with its corresponding unique identification from the second store, and means (109) if the detected formula is not in the first store, for creating a new entry for the formula in the first store. More efficient storage of formulas is thus achieved.
