Fix Google Sheet Date Formats - 20/10/2025 10:48 EDT

Job ID: 39900456

Budget: ₹1,500 – ₹12,500 INR

I have a Google Sheet that should be ready for analysis but a batch of dates was entered in mixed and inconsistent formats. Because of this the sheet can’t be filtered or sorted correctly and any formulas that rely on those dates are failing.

I need someone to come in once, clean up the date column(s), and leave the file in a state where every date is stored as a proper Google Sheets date value (not text). Prefer native techniques—Find & Replace, ARRAYFORMULA, VALUE, TO_DATE, or a quick Apps Script—so long as the end result is clean, consistent, and keeps existing data intact.

Deliverables
• All date cells converted to a single, valid format recognised by Google Sheets
• Spot-check or conditional formatting rule proving every cell is now a date value
• Brief note inside the sheet (or small TXT/MD file) summarising what you changed and how to maintain consistency in the future

This is a one-time fix; once the dates work and I can sort/filter without errors, the job is done.
