About this Gig

Your spreadsheet has the same five problems every messy file has: mixed date formats, currency symbols inside number columns, near-duplicate rows, invisible trailing whitespace, and text that turned into garbage characters in the wrong program.


I fix all five, and I give you the receipt. Every order comes back with a change report: the actual counts of what was modified, category by category. So you can check my work instead of hoping.


WHAT I HANDLE

  • Encoding repair (Shift_JIS, UTF-8, EUC-JP) for files that open as garbled text
  • - Full-width to half-width normalization, invisible whitespace removal
  • - Date, currency and phone formats unified across the sheet
  • - Duplicate rows removed, matched on the key column you choose
  • - Multiple files merged into one clean sheet

I never overwrite your original file, and I never guess. If a cell says TBD or unknown, it stays that way and gets flagged in the report. Silent corruption is worse than messy data.


Premium includes the script itself, so next time your export comes in messy you run it yourself in one command. No dependencies, no subscription.
