Check your data with blocks

You say what each column has to meet. Blockema checks the file and tells you exactly what's wrong.

Get startedSee how it works

3 reasons the error reaches the file you send.And none of them is that you are bad at Excel.

  • 01

    Half an hour that fixes nothing

    You scroll through 2,000 rows before every send and end up checking only the ones you have time for.

  • 02

    Excel only looks at one cell

    Its data validation warns you as you type, not when you paste 500 rows. And it never knows that IBAN is already 1,800 rows above.

  • 03

    The criteria change every month

    Whoever is free checks it, with the deadline on top. What gets caught one month sails through the next.

vs
With Blockema

Your rules live outside the file and run over every one that lands.

  • Reads the whole file, not cell by cell
  • Catches duplicates and rules that depend on another column
  • Built from blocks: no formulas, no IT
  • The same criteria every month, whoever opens it
  • Hands you the corrected file, not a report

Set it up once.Every file that lands after that checks itself.

You build the schema out of blocks

You drag one block for each thing a column has to meet. They read out loud like a sentence. No formulas, no scripts, nobody from IT.

And you don't start from blank: import a file you already have and it proposes the type and the rules for every column.

You open the validation and leave with the file fixed

You jump from one failure to the next and correct them right there. When you download it, your edits are applied on top of the original: your formatting and your formulas stay where they were. And if it came from Google Drive, it goes back to its folder.

Then run the same rules again in one click to confirm it's clean.

You choose where it runs.File by file.

You decide as you upload it, not in an account setting.

  • In your browser

    Default

    The file opens and is checked on your own computer. Nothing is uploaded anywhere, so there is no copy of ours to lose. Close the tab and nothing is left behind.

  • On the server

    If you prefer

    For when you want the run saved in your history, or you would rather close the tab and come back for the result later.

If data cannot leave your company, it does not. There is nothing to install, to integrate or to get signed off.

If it lands every month, you shouldn't be checking it by hand

The block you set, and the row it catches in this month’s file.

The file that goes to the bank

Payroll

Where the mistake can't be taken back: a repeated account number is two payments into the same account, and the money has already gone.
