Spreadsheet cleanup workflows
Find what is wrong with a table, fix it, then chart or hand off the result.
Do it in these steps
Popular tools
Clean a Table
1 ⚡Remove duplicates, trim spaces, split columns, find and replace, fill blank cells. Build a cleaning recipe and export the result. The file never leaves your browser.
Compare Two Tables
1 ⚡Load two Excel or CSV files and find the rows that do not match: missing entries, extra entries and changed values. Both files are read in your browser.
Fuzzy Dedupe
1 ⚡Group near-duplicate rows — the same name written differently — and export one row per group. You confirm each group yourself.
Table Validator
1 ⚡Check a table against your own rules — required, unique, ranges, patterns, date order — and export the rows that fail. Nothing is uploaded.
Pivot Table
1 ⚡Cross-tabulate your own table in the browser: pick rows, columns and a value, and the totals follow. Nothing is uploaded.
Excel to Chart
3 ⚡Upload an Excel or CSV file and get a finished chart. The file is read in your browser and never uploaded.
Table to Markdown
1 ⚡Turn a table into text you can paste: Markdown, HTML, TSV, SQL inserts, JSON, XML, YAML, LaTeX, INI, TOML, JSON Lines or an ASCII table. Nothing is uploaded.
Spreadsheet Converter
1 ⚡Convert between XLSX, CSV, TSV and JSON, right in your browser.
Merge Workbooks
1 ⚡Combine several .xlsx files into one workbook — every worksheet is carried over as it is, nothing is recalculated.
Split Workbook
1 ⚡Turn each worksheet of a .xlsx into its own file and download them as a ZIP.
