None of the free scripts quite fit? Describe what you want your sheet to do, and I’ll write the Apps Script, test it, and send it with setup steps.
Order a custom script: $49 fixed
| You ask for | You get |
|---|---|
| “When I set Status to Done, move the row to a Done tab with the date.” | An edit trigger that moves the row with formulas and formats intact, and stamps the date. Two quick edits can’t leave a row behind. |
| “Put the dates in my sheet on my Google Calendar, and keep them updated.” | A sync that creates each event once, updates it when the row changes, and stays on the right day across time zones. |
| “Students should only see the Flex tab on Tuesdays during school hours.” | A schedule that shows and hides the tab, and never tries to hide the last visible tab. |
| “Email the person who submitted the form, and CC their manager.” | A form-submit trigger with your own Gmail draft as the template. |
| “Remind people every morning about rows due this week.” | A daily trigger with one email per person, listing their rows. |
Also: custom formulas, de-duplicating or cleaning rows, importing a CSV or Gmail data, PDFs from rows, locking a range after a date.
The free scripts might already do it. If one almost does, order a custom script and say which: adapting a tested script is the fastest route.
