Example use cases
Pre-upload date integrity check
“Before I import this token holder observation file into our dashboard, can you run a calendar date check on it to catch any malformed or out-of-range dates in the observed_on column? Here's the CSV with comma delimiters.”
Automated pipeline data quality gate
“As part of our nightly token analytics pipeline, validate the date fields in this token holder observations CSV — flag any rows where the observed_on date isn't a valid calendar date or falls outside the range 2020-01-01 to 2030-12-31.”
Auditing historical token holder records
“I have a historical CSV of token holder observations and I need to audit it for date errors — can you check that all the observed_on values are legitimate calendar dates and give me a report of which rows have problems?”
