Why did my Airtable record count suddenly jump?
The Airtable help pages give 3 common reasons. The first to rule out: If your plan includes the CSV import extension, an import run with merging left off creates new records from the file instead of updating existing ones.
What causes it?
If your plan includes the CSV import extension, an import run with merging left off creates new records from the file instead of updating existing ones.
In the Airtable help:
If you want to create new records with your CSV data, keep this option toggled off.
CSV import extension, read 2026-11-12.Even with merging on, rows in the file that match no existing record are added as new records.
In the Airtable help:
If the CSV being imported contains rows which have no matches in the table, the extension will create new records.
CSV import extension, read 2026-11-12.Rows with an empty value in the field used for merging are added as new records.
In the Airtable help:
If the CSV contains any rows where the value in the merge field is blank, a new record will be created.

How do I check it myself?
If your plan includes the dedupe extension, use it to find duplicate records in the table.
In the Airtable help:
The dedupe extension helps you find and manage duplicate records in a table.
Dedupe extension, read 2026-11-12.If you search for duplicates with fuzzy matching, review each match, since it can flag records that are not duplicates.
In the Airtable help:
Fuzzy matching can often result in false positive matches, since its search is so broad.
Dedupe extension, read 2026-11-12.Before the next import, read the counts of records to be updated, left unchanged and created, to catch an import that would add more records than you expect.
In the Airtable help:
The bottom of the extension window will show the number of records that will be updated, the number of records that won't change, and the number of new records that will be created (if any).
CSV import extension, read 2026-11-12.
How does Airtable work with Feder?
- Connect Airtable to Feder and it joins your Interest apps.
- When you connect Airtable, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Airtable, one of your Interest apps. Feder only reads. It never changes anything in Airtable.
