Hash marks that hide a real 18:45<\/h2>\n

A cell full of hash marks often means the column is narrower than the formatted time. 18:45 can be sitting underneath, correct and invisible. Widen the column before you touch the value. If widening reveals 18:45, you are done with that cell. If widening reveals a date in 1900 or a fraction, you have a value problem and the width was a coincidence. The order is widen, look, then decide. Re-entering 18:45 into a hash-mark cell without looking will overwrite a good value with whatever you remember.<\/p>\n

Check the neighbor cell 12:00 the same way. A column that hashes 18:45 and shows 12:00 is narrow for the longer display, not corrupt. A column that hashes both is either extremely narrow or actually broken. The pair tells you which. One cell cannot.<\/p>\n

Fraction 0.78125 that should be 18:45<\/h2>\n

Excel stores 18:45 as a fraction of a day. 18.75 hours divided by 24 is 0.78125. If you see 0.78125, format as time before you assume the sheet forgot the appointment. The appointment may be there. A coworker who “corrects” 0.78125 by typing 1845 as text has destroyed a real time and left a label. Format first. The format you want shows 18:45. Then lock the format so the next paste does not bring General back.<\/p>\n

Keep a note in the header: “0.78125 is 18:45, do not retype.” People fear fractions and they retype. The note is for them. It can cite one example only. A note that lists every fraction is a second spreadsheet. One example teaches the pattern.<\/p>\n

CSV that turned 08:05 into 8:05 and then into 805<\/h2>\n

A CSV export may strip the leading zero, and a later import may strip the colon, leaving 805. 0805 is five minutes past eight in the morning. 805 is a three-digit string that will sort badly and may be read as 8:05 or as 20:05 by two different importers. Restore the zero in a text pass that checks length. Four digits, or a colon form with a leading zero. Reject 805 into a quarantine column. Do not auto-guess. Guessing is how half the rows become evening.<\/p>\n

The quarantine check is a known morning: the source had 08:05, the file should not contain 805 or 8:05 without a leading zero if your standard is four digits. One known row earns the right to quarantine the rest. A quarantine with no known row is a pile.<\/p>\n

Chart axis that plots text 1845 at the wrong x<\/h2>\n

A chart built on text stamps will plot “1845” near “1900” in alphabetical space, which might look fine, and will plot “900” in a ridiculous place. Convert the axis to real times, then check that 18:45 sits after 12:00 and before 21:00. If the point for 18:45 appears before noon, the axis is still text or the value is still a fraction being read as a day count in the wrong unit. Fix the axis source. Do not drag the point. A dragged point is fan fiction.<\/p>\n

Quarantine tab named 805-needs-a-zero<\/h2>\n

The quarantine tab should be named for the failure, “805-needs-a-zero,” not “misc” and not “fixed.” 805 is the three-digit leftover of 08:05. A name that states the repair tells the next person what not to do. They must not add a trailing zero. They must add a leading zero or restore the colon form, then move the row back only after 0805 or 08:05 survives a reload.<\/p>\n

Count the quarantine before and after the repair. If you started with forty rows and ended with forty in the live sheet plus six still quarantined, say so. A repair that “clears the tab” by deleting the six is not a repair. Those six are still someone’s morning. 08:05 is one of them. Deleting it makes the sheet look obedient and the yard late.<\/p>\n","protected":false},"excerpt":{"rendered":"
