Clean up a messy Excel export — free.
Let your agent work across all your spreadsheets for you.
Upload a spreadsheet and get a tidy copy back. We trim stray spaces, turn numbers that got stored as text back into real numbers, drop duplicate rows, and standardize inconsistent values — then show you a plain-language list of every change. Anything that needs your judgment is left untouched, and your original workbook is never changed.
What it cleans
The cleaner runs a full sweep for the grime that piles up in exported spreadsheets: stray leading and trailing spaces, numbers stored as text, fully-duplicate rows, empty trailing rows, inconsistent “not available” markers, mixed date formats, and label spellings that should match but don’t. Each fix is applied only when it’s unambiguously safe.
The before→after ledger is the point
Nothing changes silently. Every fix shows up under what we did, and anything we deliberately left alone — blank cells we won’t invent data for, a column of repeated values that’s yours to keep or drop — shows up under what we didn’t touch, with the reason. You see the whole picture before you download.
Your original file is safe
The page reads your file in memory, cleans a copy, and double-checks that copy opens
the same in two independent spreadsheet engines. Your uploaded .xlsx is never
changed and never stored — you download a fresh, clean file, so nothing is ever lost.
