Diffslip CSV Change Ledger

Diffslip turns two CSV exports into a focused, inspectable change ledger. Import a before and after file from Files, choose a shared column such as SKU or ID, and compare records by that key instead of by row position. See which records were added, removed or modified. Open a changed row to inspect the exact before and after value for each affected field. An unchanged count helps reconcile the two versions. Diffslip stops when a key is blank or duplicated, when headers conflict, or when a row has the wrong number of cells, so an ambiguous comparison is never presented as a clean result. Save several named comparisons on this device. Preview a real PDF review sheet, share it with a colleague, or export a named CSV change log for follow-up. Both exports preserve the original source values; Diffslip does not edit the imported files. Supported inputs are UTF-8 CSV files up to 20 MB with a header row and consistent columns. Comma, semicolon and tab delimiters are recognized. Diffslip compares text values exactly; it does not normalize currencies, dates, units or case. Review the chosen key and the result before acting on changes. One purchase, with no account, subscription, ads, analytics, tracking or developer upload. Imported files and saved comparisons stay on this device unless you choose to share an export.
