User Behavior Trend Data Entry

I’m putting together a clean, analysis-ready dataset so I can study user-behavior trends over time. Right now the raw records have missing or inconsistent date information, which means any trend analysis I run will be unreliable.

Here’s what I need from you: take the source file I’ll provide (CSV) and accurately enter or correct every date field so each row has a valid, uniformly formatted date (YYYY-MM-DD). If a date is unclear, leave a brief note in a separate comments column so I can verify it later.

Once complete, send back:
• the updated CSV/Excel file with all date fields fixed and validated
• a short log summarising any rows you flagged for review

I’ll be checking that every date is present, correctly formatted, and consistent with adjacent time-stamp data before moving on to the actual trend analysis. Familiarity with Excel or Google Sheets validation tools will make the job faster, but manual accuracy is what matters most here.
