How to use Find Data in CSV
- 1. Paste the CSV to search. Put the data in the input pane. It can be a handful of rows or a large export; every cell is scanned, not just whole lines, so matches inside quoted fields are found too.
- 2. Enter the search term. Type what you are looking for into Find. Enable Case-sensitive when Ada and ADA must be treated as different values, or leave it off for a forgiving search.
- 3. Tell it about the header. With First row is header ticked, matches are reported with the column's name as well as its number, so a hit reads like row 2, column 1 (name) instead of bare coordinates.
- 4. Copy the list of locations. The output lists every matching cell with its row, column and value. Copy it to document where a value hides, or use the coordinates in a follow-up edit.
When to use Find Data in CSV
Find Data in CSV tells you where a value lives, not just whether it exists. Ctrl+F in a text editor finds the characters but leaves you counting commas to figure out the column; this tool reports exact row and column coordinates for every matching cell.
- Locating a customer in a big export. Support asks which record holds a specific email address in a 10,000-row dump. Search here and get the row number to hand straight to whoever fixes it.
- Finding which column holds a value. An import failed on the value N/A somewhere in the file. Searching reveals every cell containing it, including the column names, so you know which fields to clean.
- Tracking down duplicated identifiers. An order ID should appear once but the report shows it twice. Searching for the ID lists both cell locations so you can inspect the surrounding rows.
- Verifying a value made it through a pipeline. After a transformation job runs, search the output file for a known marker value. Its presence at the expected coordinates confirms the mapping worked.

About the Find Data in CSV tool
Find Data in CSV runs as plain JavaScript in your browser tab, with no server behind it. Find CSV cells that contain certain data. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's CSV Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 3 settings, including Find, Case-sensitive and First row is header, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
