TableSafe / Spreadsheet imports
Keep the zeros. Keep the identifiers.
Turn a copied table or CSV into a spreadsheet with explicit column types. Preview date decisions and block conversions that would round long identifiers.
Free checks work here without installing anything or signing in. The optional Chrome extension is awaiting store availability.
Try one real task.
Full preview, explicit conversion checks, and a 10-row CSV sample. Use the included example to inspect a Pro output at no cost.
The mistake it catches
An identifier such as 001027 stays a text cell. A 18-digit reference stays exact. Ambiguous dates stay text until you choose a format.
Where it fits
For operations teams importing customer IDs, orders and financial tables.
It complements your existing workflow. Checks have a defined scope, and outputs tell you what remains untested.
A short guide to the task.
Use the extension when capture helps.
You can paste your input and run free checks here first. The optional extension captures from the page you invoke it on. Until its store listing is available, the ZIP requires Chrome developer mode.
