About this tool
A CSV file that looks fine in a spreadsheet can still be rejected by the system you are importing it into — often with an error message that doesn't say what is actually wrong.
This tool is being built to identify formatting and compatibility problems in CSV files, explain them in plain language, and help you repair them so the import works.
Useful for
- Operations and data teams
- Finance teams importing records
- Anyone moving data between systems
Your files and privacy
Before launch, this section will state exactly where your files are processed — in your browser or on our servers — and how long, if at all, anything is kept. We prefer in-browser processing wherever it’s practical.
PuffinKit never changes your original files. See our privacy policy.
Frequently asked questions
Will it be free?
PuffinKit is free-first: the aim is that ordinary tasks can be completed for free, without creating an account. If this tool has any limits, they will be stated on this page before you upload anything — never after you have done the work.
Where will my files be processed?
This will be stated clearly on this page before the tool launches: whether files are processed in your browser or on our servers, and how long, if at all, anything is kept.
Can I suggest a feature or ask a question about it?
Yes, please do. Your input helps shape the tool before it launches. Contact us with what you need it to handle.
