Import and Export

MikroSheets stores multiple local workbooks in the browser workbook library. It also supports two portable data paths: CSV for the current sheet, and MikroSheets JSON for full workbook backup and restore.

Local Workbook Library

Use the library button to open another local workbook, create a new workbook, rename, duplicate, or delete workbooks stored in this browser profile.

The library is local to the current site and browser profile. Export JSON when a workbook needs to move to another device, another browser, or another MikroSheets deployment.

Import CSV

Use the CSV import button when you have a plain table from another tool. CSV import writes rows and columns into the current sheet.

CSV does not preserve MikroSheets-specific data such as multiple sheets, comments, revisions, structured views, field settings, links, or formatting.

For quick one-off transfer, you can also copy a rectangular range from Numbers, Excel, or another spreadsheet and paste it directly into the selected MikroSheets cell.

Export CSV

Use the CSV export button when you need the current sheet in a format that opens in spreadsheet tools, data tools, or text editors.

Import JSON

Use the JSON import button for MikroSheets backups and example workbooks. JSON import restores the workbook structure that CSV cannot represent.

Export JSON

Use the JSON export button when you want a durable backup or want to move a workbook to another browser profile, device, or deployment.

Export JSON before clearing browser data, moving domains, switching profiles, or testing risky edits on an important workbook.

Choosing a Format

Use CSV for simple one-sheet exchange. Use JSON for backup, restore, and MikroSheets-to-MikroSheets movement.

Use the print button when you need a paper/PDF copy of the active sheet.

Unsupported Formats

XLSX import/export is intentionally deferred in the 1.0.0 release while MikroSheets keeps the browser runtime small, static-hosted, and local-first.
