What it does
Six tools, one price
CSV Cleaner, CSV Compare, CSV Split & Merge, Bank Statement Normalizer, Shopify Product CSV Mapper and JSON to CSV Converter. Bought one by one they cost USD 95; the toolkit is USD 49.
Identical to the single products
Every HTML file in the toolkit is byte-identical to the one sold on its own, and the checksums are in MANIFEST.sha256.
Your files stay put
Each page is blocked from using the network, so customer lists, statements and supplier prices never leave your computer.
Tested the same way
Each tool is tested against an independent reference implementation on hundreds of generated files and run through the real page in Chrome, Firefox and WebKit with 0 network requests.

Who it is for
- People who would use several of these tools: bookkeepers, online shop owners, analysts and office admins who handle CSV exports.
- Anyone who prefers one download and one licence over six separate purchases.
Honest limits
- None of the six tools opens .xlsx workbooks. Save the sheet as CSV first.
- The Shopify tool has not been tested by importing into a live Shopify store.
- Nothing in the toolkit has been tested in Microsoft Excel. Each tool's README lists what was and was not tested.
- Safari itself was not tested. WebKit, the engine behind Safari, was.
Details
- Included: Six folders (each with its HTML file, README, sample files and licence), a top-level README, the licence, and SHA-256 checksums for every file.
