Question 1

Is this tool free?

Accepted Answer

Yes, completely free, no signup required.

Question 2

Is my data sent to a server?

Accepted Answer

No, parsing runs entirely in your browser as you type or paste.

Question 3

Does it handle data copied directly from Excel or Google Sheets?

Accepted Answer

Yes, copying cells from a spreadsheet produces tab-separated data, which the auto delimiter detection recognizes without any configuration.

Question 4

Does it handle commas inside a quoted value correctly?

Accepted Answer

Yes, a field like "New York, NY" stays as a single value instead of being split into two, the parser follows standard CSV quoting rules rather than naively splitting on every delimiter character.

Question 5

What delimiters are supported?

Accepted Answer

Tab, comma, semicolon, and pipe, plus an auto-detect mode that picks whichever delimiter appears most often in the first line.

Question 6

What is the difference between the three output formats?

Accepted Answer

Flat joins every value into one comma-separated list, Associative outputs each row as an object keyed by the header row, and Multidimensional outputs a plain array of arrays, one per row.

Question 7

What does "First row is header" do?

Accepted Answer

When on, the first row is treated as column names and excluded from the row count and from the Multidimensional and Flat outputs' data rows, Associative mode always requires it since it uses those names as object keys.

Question 8

What does "Auto-convert types" do?

Accepted Answer

It converts values that look like numbers, such as 30 or 98.5, into actual numeric values in the output instead of leaving every value as a quoted string.

Question 9

Does it convert boolean-looking values like true or false?

Accepted Answer

No, only numeric-looking values are coerced, text like true or false stays as a string.

Question 10

Can I choose single or double quotes in the output?

Accepted Answer

Yes, the Quotes toggle controls whether string values in the generated array are wrapped in double or single quotes.

Question 11

Does the table preview show every row for a large paste?

Accepted Answer

It shows up to 200 rows at a time and tells you how many more there are, the full parsed data is still available in the raw output, this limit only applies to the table view for performance.

Question 12

Can I copy the output?

Accepted Answer

Yes, both the input and output panels have their own Copy button.

Question 13

Does it require an account?

Accepted Answer

No, the tool works anonymously with no signup.

Question 14

Is there an API for this?

Accepted Answer

Yes, /api/tools/csv-to-array accepts { input } and returns a JSON array plus the raw output string, the delimiter, quoting, output format, and type coercion options are currently features of the browser tool.

Question 15

Can I load a sample to try it out?

Accepted Answer

Yes, the Example button fills in sample data matched to the currently selected delimiter, including a quoted field with an embedded comma.

Question 16

What happens with an empty line in my pasted data?

Accepted Answer

Rows are parsed line by line, an empty line at the end of your paste is trimmed automatically rather than producing a stray empty row.

Question 17

Does it handle a header row with fewer columns than the data?

Accepted Answer

Associative mode maps each data row to the header row by position, if a data row has more or fewer columns than the header, extra values are dropped and missing ones come out empty.

Question 18

What happens if my data uses inconsistent delimiters?

Accepted Answer

Auto-detect picks the delimiter that occurs most often in the first line and applies it to the whole paste, if your data genuinely mixes delimiters, pick the correct one manually instead of relying on auto-detect.

Question 19

Does the tool tell me how many rows and columns it parsed?

Accepted Answer

Yes, the status bar reports the row count, column count, and which delimiter was used, including whether it was auto-detected.

Question 20

Why would I use this instead of writing a CSV parser myself?

Accepted Answer

Correctly handling quoted fields, escaped quotes, and mixed delimiters takes more edge-case handling than it looks like, this tool has already worked through those cases for a one-off paste-and-convert task.
