Know what the tools offer.
CHERN Tools provides focused local spreadsheet workflows and a batch-cost scenario calculator. It does not replace your source records or your review of a business decision.
Use the documented workflow
Read the tool guide, try the synthetic example, choose the rules, check the inputs and review the exported result. Keep your original files. Future plans do not describe functions that are available today.
Check assumptions and results
The tools support your judgment. Before relying on any output, review the selected rules, warnings and source data. Illustrations use synthetic identifiers and are not business advice or manufacturing quotations.
Responsible use
Do not send confidential company materials, personal data or restricted third-party content through feedback channels. Do not attempt to run macros or other code through the site. Local processing does not remove your responsibility to handle your own files appropriately.
