A grid for plain CSV files.

The grid is the CSV. Free on iPhone, iPad, and Mac.

Why FlatGrid

Three promises

01
Open it. Use it. Done.
This tool isn't needy. It doesn't ask for anything. It just works.
02
Simple as 1 + 1 = 2.
See the math right below the total. Check it yourself. Nothing to hide.
03
Your business is none of ours.
No accounts. No tracking. No subscriptions. We don't take your data.

What it does

A grid on top of a plain file

FlatGrid opens a CSV and shows it as a grid. Edit a cell and the file changes. The grid is the CSV.

Every cell stays exactly as you typed it. 00123 stays 00123. Dates stay in the layout you wrote them.

Add a sum, average, count, smallest, or largest value to any column. The total sits under the column, and the line below it lists every number that went into it, row by row.

Your tables live in a folder you choose, in Files or Finder. Open them in any spreadsheet, on any device. FlatGrid is free, with every feature included.

On disk

The artifact is canonical

table.csvSource of truth. The grid shows it and edits it in place.
*.tsvSame law. Tabs instead of commas. Still a file.
folder/Related tables sit next to each other, where you put them.

The Flat family

Flat Apps. Software that minds its own business.

If FlatGrid disappeared tomorrow, your CSV would still open in anything that reads a table.
