Free Google Sheets Tools — Plus CSV, Excel and More

Eight in-browser tools to clean, convert, and combine any spreadsheet

Fix messy spreadsheets in your browser. No upload, no account, no limits. Convert between formats, remove duplicates, filter, find-and-replace, merge, sort, split, or VLOOKUP-join — on CSV, Excel, Google Sheets, BigQuery queries, or REST API data. Use them once or come back anytime. When the same job starts repeating, turn it into a scheduled Sheetgo workflow.

V

Convert

CSV, Excel, Google Sheets, BigQuery, and REST APIs — convert between any format instantly.
N

Remove Duplicates

Delete duplicate rows across all columns or a selected subset. Keep first or last occurrence.
R

Filter

Keep only rows that match your condition — equals, contains, greater than, empty, and more.
U

Find and Replace

Bulk replace text across a file — exact or substring, case-sensitive, column-scoped.
_

Merge

Stack rows from multiple files into one master sheet. Multi-row headers supported.
?

Sort

Sort by up to three columns, ascending or descending — all formats supported.
`

Split

Break one sheet into many — one file or tab per unique value in a chosen column.
>

VLOOKUP

Join two spreadsheets by a shared column — Inner or Left Join, pick output columns.

Ready to automate the same jobs every week?

These eight tools solve one-off jobs. When the same job comes back every week or month, that’s where Sheetgo comes in. The Google Workspace add-on schedules any of these operations unattended, chains them into multi-step flows, generates documents and emails from your data, and pipes results straight into Google Sheets, Excel, or your downstream reports.
