A careful path from spreadsheet to system

Make the first clean employee record.

Hand over the exports your client actually sent you. SchemaBridge matches the columns, cleans what is safe to clean, and stops only when a choice would change what gets migrated.

Free with synthetic data only. 20 private starts per account daily, or 100 shared guest starts.

Start date needs a decision

2 April 2026 or 30 November 2024?

From raw files to a reviewable result

A migration with a clear next step

  1. 1

    Add the exports

    CSV or Excel, more than one at a time. Different column names in each file are expected, not a problem.

  2. 2

    Watch it work

    Columns matched, duplicate rows combined, dates and spellings standardised — every step recorded with its reason.

  3. 3

    Answer what it cannot decide

    Two files disagree about a start date? It asks you, shows both sources side by side, and does nothing until you choose.

It decides on its own when it is safe to

  • Matches emp_nm, Employee Code and doj onto the right fields without being told
  • Combines rows for the same employee when the files agree
  • Trims stray spaces, fixes casing, and writes dates one way
  • Keeps leading zeros — 000123 stays 000123
  • Sends valid records to the destination and retries the ones that fail for a transient reason

It stops when guessing would be wrong

  • 03/04/2026 — that is two real dates, so it asks which one
  • Two files with different start dates for the same employee
  • A column nothing in the destination corresponds to
  • An address that is still invalid after a repair was attempted
  • A record the destination itself refuses, with the destination’s own reason shown

The boundary is part of the product

What it does not do

Plainly, so nothing here is a surprise later.

It is a demo destination
Records go to a simulated HR system inside this app. Nothing is sent anywhere else.
Synthetic data only
Do not upload real personal information. Guest uploads are deleted after two days; private Google workspaces after seven.
Schemas need review
Build, import, or detect a target shape, then confirm its fields before relying on it for a client.
Small files
A few thousand rows at most — this is a workbench, not a batch pipeline.
