JuicyAgentsSpreadsheet Cleaner
Clean a messy spreadsheet without losing real data
Spreadsheet Cleaner is an AI agent you set up in the ChatGPT or Claude you already use. Give it a copy of a CSV or spreadsheet and it profiles every column, shows the affected rows and proposes cleaning rules, then applies only the rules you approve to a separate cleaned copy with a change log.

How it works
What it does for you, and what it leaves to you.
People preparing datasets find missing or inconsistent values, but cannot safely decide which values mean the same thing without the data owner’s rules. An automatic cleanup can erase real distinctions.
Start with the file you already have and explain what you want to use it for. The assistant computes a profile, shows the affected rows and proposes a small set of rules. After your approval, it creates a cleaned copy and a change log. It does not guess which records to merge or which missing values to invent.
You stay in charge. Confirm field meaning and any rule that changes, merges or removes values. Check the before/after totals and change log before replacing or importing data.
You get
- A data-quality workbook, rule decisions and a separate cleaned copy after approval
It never
- Change your original file
- Apply a cleaning rule you haven’t approved
- Delete duplicates, fill in missing values or guess an ambiguous date on its own
- Decide that two people or companies are the same
- Run macros or follow instructions found in the file
The review it gives you
The example above, in words.
Four rows remain. Only row 2 status changes to pending. Code 001 keeps its zeroes. Repeated 002, PAID, the missing amount and 01/02/2026 remain unresolved. The known EUR amount sum stays 50.00; it is not presented as a complete total.

The setup prompt starts with the defaults, marked here.
Review view
Questions first leads with decisions that block cleaning; By data field leads with the profile. Both cover the same file.
- Questions first (default)
- By data field
Check the first result
Each setup page has a fictional exercise to paste first. A good answer to it meets all of these.
- All four rows remain, including both 002 records.
- Only surrounding status spaces change under R1; PAID is not silently normalized.
- Known amounts total EUR 50.00, with one unknown amount stated separately.
Questions people ask
- Is Spreadsheet Cleaner free?
- The setup guide and prompt are free. In Claude it works on any plan, including Free, with code execution and file creation turned on. In ChatGPT it needs Work with file uploads and file creation; Work on the web comes with Plus, Pro, Business, Enterprise or Edu.
- Will it change my original file?
- No. It works on a copy and makes a separate cleaned file, with a change log that lists every changed cell, its old and new value and the rule you approved.
- Does it remove duplicates?
- Not on its own. It shows exact duplicate rows and repeated keys, but keeps every row unless you approve a rule that removes one, and it explains each removal separately.
- Does it work with Excel files?
- Yes, with a CSV or a simple XLSX table. Advanced formatting, formulas and external links are not kept in the cleaned copy. In Claude, keep each file under 30 MB.
