Ruankao Information Processing Technician (Junior) · Understand the traps and how to avoid them.
Treating a renamed extension as proof that a file was converted.
The name and the internal representation are different evidence.
What to do instead
Use the appropriate verified export/conversion feature and inspect the resulting content and format rather than merely changing the filename.
Assuming AutoRecover or synchronization is a complete independent backup.
Temporary recovery state or propagated changes may not protect against deletion or corruption.
What to do instead
Keep a recovery plan with suitable retained history and independence, and test restoration under the actual application and storage behavior.
Using repeated spaces and blank paragraphs as a stable page-layout method.
Font or content changes can shift the layout and make manual spacing fragile.
What to do instead
Use styles, paragraph spacing, tabs/tables and the appropriate page or section boundaries, then inspect printed or exported output.
Sending a mail merge without checking the actual recipient records.
Missing fields or a wrong selection can personalize or disclose information incorrectly.
What to do instead
Preview representative and boundary records, verify the recipient selection and output, and use the actual authorization process before sending.
Copying a formula without checking which references moved.
The copied coordinates can change a tax, rate or source relationship unintentionally.
What to do instead
Trace relative, absolute and mixed references from the original and destination cells, and verify the result with a simple independently computed example.
Sorting one column while leaving the associated records in place.
The operation can detach each label from its correct values.
What to do instead
Select the intended table, check headers and complete records, and verify a sample before and after the sort.
Assuming an embedded or linked chart will always refresh correctly for every recipient.
Link availability, permissions and the application model affect what can be updated.
What to do instead
State whether the object is linked, embedded or exported, test access and refresh behavior, and inspect the delivered values and labels.
Treating a padlock as proof that a website is honest.
Encrypted transport and certificate validation do not establish the truth of the website’s claims.
What to do instead
Check the intended destination and request, verify suspicious actions through a known channel, and use appropriate account and sharing controls.
