YOUR WORKSPACE
Join two spreadsheets free online by key, compare changed fields and choose left, inner, right or full joins. Review repeated keys, expanded rows and unmatched records.
The comparison sample has three original A rows and four B rows. Compare by ID to find two items: DEMO-002 changes from 200 to 250, and DEMO-004 appears only on the right.
Imports allow up to 50 files, 50 MB, 100,000 rows, 300 fields and 2 million cells; result limits also apply. One-to-many joins can expand results considerably. Comparisons and joins always use the selected original tables, not automatically adopted working data. Field comparisons do not infer semantic equivalence.
No. It uses retained original tables. Download cleaned output and reimport it when comparing cleaned versions.
They create multiple possible counterparts for a record. Review the business rule or use one-to-many joining to inspect relationships.
Use the local functions for free without a KitNelo account. Optional Gemini generation sends the supplied text to Google and requires a configured server API key; provider fees and quotas can apply.
Repeated keys can expand row counts. Check match cardinality and unmatched rows before accepting the joined table.
Read KitNelo data and privacy detailsLoad the two tables and select the corresponding key columns to match their records. Review duplicates and unmatched keys before accepting the output, since repeated values can create multiple matches and expand the number of joined rows.
Match two CSV tables by their selected keys and inspect differences in the fields you want to compare. Check that key formatting and column mappings agree so whitespace, identifiers or mismatched fields do not create misleading changes.
Choose a join type to control which matched and unmatched records appear in the result. Review the output row count and missing fields, paying particular attention to one-to-many matches before exporting a combined table.
