Rename file copies from Excel, CSV or naming rules
- Select a flat batch of files; the originals stay unchanged.
- Set naming rules, or import CSV/XLSX and choose the worksheet and mapping columns.
- Review changed and unchanged names, and fix collisions or invalid names.
- Create a ZIP, download the renamed copies and keep the rename list.
Formats, output and limits
Inputs: any selected file types, with optional CSV or XLSX mapping. Output: ZIP containing unchanged source bytes under the approved names, plus a CSV manifest. This does not rename files on disk or convert formats.
Spreadsheet-safe CSV: risky text gets the visible prefix text: . Preview: =1+1 becomes text: =1+1; full-width formula starters and leading control characters are handled too. Validated numeric amounts keep their signs. Use JSON, where available, for original text and XLSX for typed exchange.
File tools accept up to 50 files and 100 MiB total, with a maximum of 500 source PDF pages. Mapping imports allow 10,000 rows. These are resource caps, not guarantees for every device. See all limits and troubleshooting.
A worked example
Map scan001.pdf to Quotation-001.pdf. If two rows propose the same name, correct the mapping before creating a ZIP. An unmatched source keeps its original name.
Common questions
Will this change my original files?
No. The tool downloads renamed copies. ZIP entries contain the same file bytes as the selected inputs.
Which mapping columns are needed?
Use headers and columns for complete original filename and proposed new filename. You choose the worksheet and columns. Original names must match exactly, including extensions. Formula cells used for mapping are rejected.
What happens to extensions and duplicates?
The original extension is preserved. New names may omit it or include the same extension. A conflicting extension is rejected because renaming cannot convert file contents. Duplicate keys and case-insensitive or Unicode-normalized output collisions block export.
