  "Description": "Spreadsheets silently turn entries such as '30.3' into\ndates, so the imported data carry date serials instead of the\nnumbers that were typed. Reading the workbook directly recovers\nthose numbers without guesswork: an 'xlsx' file states its own\ndate system, and records which cells are formatted as dates and\nin which field order, so the values to repair are identified\nfrom the file rather than inferred from their magnitude.\nFunctions are also provided for data already imported, where\nthat evidence is no longer available, using conservative and\nconfigurable detection.",
