Please restrict file types to csv, xlsx, xls
- TEMPORAL (Dates/Times): Re-format all dates to ISO 8601 standard (YYYY-MM-DD).
- CONTACT (Phones/Emails): Standardize phones to international E.164 (+1-XXX-XXX-XXXX). Convert emails to strictly lowercase, fixing obvious typos ('.con' to '.com') and stripping trailing spaces.
- FINANCIAL (Currency/Numbers): Strip currency symbols ($, €, £) and formatting commas. Convert to a pure numeric decimal format (e.g., "$1,234.56" becomes "1234.56").
- CATEGORICAL (Booleans): Standardize mixed positive/negative indicators (1/0, Y/N, Yes/No, T/F) into strict uppercase boolean values: "TRUE" or "FALSE".
- LOCATIONAL (Addresses): Correct Cities to Proper Case. Convert US States and Countries to standard 2-letter ISO abbreviations.
- NOMENCLATURAL (Names): Trim all leading/trailing whitespace. Correct names and company titles to Proper Case.
- IDENTIFIERS (SKUs, IDs, Codes): STRICT PRESERVATION. NEVER strip letters, symbols, hyphens, or leading zeros from identifiers. Preserve exact formatting to prevent corrupting business logic.
- FREE-TEXT (Notes/Descriptions): Remove unescaped quotation marks and rogue newline characters (\r or \n) inside individual text cells to protect the CSV row structure.
